To list the gpu-group objects present on a platform, use xe gpu-group-list. To view detailed information about a gpu-group , use xe gpu-group-param-list :.
A vgpu object represents a virtual GPU. Instead, they are created as follows:. Use xe vgpu-create to create a vgpu object, specifying the type of vGPU required, the GPU group it will be allocated from, and the VM it is associated with:. Instead, the vgpu object is created whenever its associated VM is started. The owning VM must be in the powered-off state in order for the vgpu-create command to succeed. To change the type of vGPU allocated to a VM, delete the existing vgpu object and create another one.
XenServer creates GPU groups with a default allocation policy of depth-first. To change the allocation policy of a GPU group, use gpu-group-param-set :. Create a vgpu object with the passthrough vGPU type:. Without the optimized networking and storage drivers that the XenServer tools provide, remote graphics applications running on GRID vGPU will not deliver maximum performance.
The console VGA interface in vGPU is optimized to consume minimal resources, but when a system is loaded with a high number of VMs, disabling the console VGA interface entirely may yield some performance benefit. If you disable console VGA before you have installed or enabled an alternate mechanism to access the VM such as XenDesktop , you will not be able to interact with the VM once it has booted.
These platforms are typically configured to operate in Non-Uniform Memory Access NUMA mode; physical memory is arranged sequentially in the address space, with all the memory attached to each socket appearing in a single contiguous block of addresses. See GPU allocation policy for details on switching the allocation policy to breadth-first.

This mechanism is not supported alongside the XenCenter UI and xe vgpu mechanisms, and attempts to use it may lead to undefined results. A virtual disk has been created. Ensure that the following prerequisites are met: Windows Server with Desktop Experience and the Hyper-V role are installed and configured on your server platform, and a VM is created.
Note: You can assign a pass-through GPU to only one virtual machine at a time. Update xorg. Verifying operation with nvidia-settings. Frame rate is capped at 3 frames per second. GPU resource allocations are limited, which will prevent some applications from running correctly. These restrictions are removed when a license is acquired. This policy generally leads to higher performance because it attempts to minimize sharing of physical GPUs, but it may artificially limit the total number of vGPUs that can run.
This policy generally leads to higher density of vGPUs, particularly when different types of vGPUs are being run, but may result in lower performance because it attempts to maximize sharing of physical GPUs.
Each hypervisor uses a different GPU allocation policy by default. You can monitor the performance of pass-through GPUs only from within the guest VM that is using them.

Virtual Application User. Possesses administrative permissions for all objects underneath a specific data center except for storage.
Possesses administrative permissions for all objects underneath a specific cluster. Possesses administrative permissions for all operations on a specific logical network.
Can configure and manage networks attached to virtual machines. To configure port mirroring on a virtual machine network, apply the NetworkAdmin role on the network and the UserVmManager role on the virtual machine.
The table below describes the user roles and privileges applicable to virtual machine users. These roles allow access to the VM Portal for managing and accessing virtual machines, but they do not confer any permissions for the Administration Portal. Apply this role to a user for the whole environment with the Configure window, or for specific data centers or clusters.
For example, if a PowerUserRole is applied on a data center level, the PowerUser can create virtual machines and templates in the data center. Can manage virtual machines and create and use snapshots. A user who creates a virtual machine in the VM Portal is automatically assigned the UserVmManager role on the machine. This role is not applied to a specific virtual machine; apply this role to a user for the whole environment with the Configure window. When applying this role to a cluster, you must also apply the DiskCreator role on an entire data center, or on specific storage domains.
If the Allow all users to use this Network option was selected when a logical network is created, VnicProfileUser permissions are assigned to all users for the logical network.
Users can then attach or detach virtual machine network interfaces to or from the logical network. If you are creating virtual machines for users other than yourself, you have to assign roles to the users before they can use the virtual machines. Note that permissions can only be assigned to existing users. See Users and Roles in the Administration Guide for details on creating user accounts. However, customized roles can be configured via the Administration Portal.
The default roles are described below. A User can connect to and use virtual machines. This role is suitable for desktop end users performing day-to-day tasks.
A PowerUser can create virtual machines and view virtual resources. This role is suitable if you are an administrator or manager who needs to provide virtual resources for your employees. A UserVmManager can edit and remove virtual machines, assign user permissions, use snapshots and use templates. It is suitable if you need to make configuration changes to your virtual environment. When you create a virtual machine, you automatically inherit UserVmManager privileges.
This enables you to make changes to the virtual machine and assign permissions to the users you manage, or users who are in your Identity Management IdM or RHDS group.
Enter a name, or user name, or part thereof in the Search text box, and click Go. A list of possible matches display in the results list.
If a user is assigned permissions to only one virtual machine, single sign-on SSO can be configured for the virtual machine. With single sign-on enabled, when a user logs in to the VM Portal, and then connects to a virtual machine through, for example, a SPICE console, users are automatically logged in to the virtual machine and do not need to type in the user name and password again.
Single sign-on can be enabled or disabled on a per virtual machine basis. See Configuring Single Sign-On for Virtual Machines for more information on how to enable and disable single sign-on for virtual machines. Click Remove. A warning message displays, asking you to confirm removal of the selected permissions. Take a snapshot of a virtual machine before you make a change to it that may have unintended consequences. You can use a snapshot to return a virtual machine to a previous state.
If no disks are selected, a partial snapshot of the virtual machine, without a disk, is created. You can preview this snapshot to view the configuration of the virtual machine.
Note that committing a partial snapshot will result in a virtual machine without a disk. The snapshot is created with a status of Locked , which changes to Ok. When you click the snapshot, its details are shown on the General , Disks , Network Interfaces , and Installed Applications drop-down views in the Snapshots tab.
Click the Preview drop-down menu button and select Custom. This allows you to create and restore from a customized snapshot using the configuration and disk s from multiple snapshots. The status of the snapshot changes to Preview Mode. The status of the virtual machine briefly changes to Image Locked before returning to Down. Click Commit to permanently restore the virtual machine to the condition of the snapshot. Any subsequent snapshots are erased.
Alternatively, click the Undo button to deactivate the snapshot and return the virtual machine to its previous state. After a short time, the cloned virtual machine appears in the Virtual Machines tab in the navigation pane with a status of Image Locked.
The virtual machine remains in this state until oVirt completes the creation of the virtual machine. A virtual machine with a preallocated 20 GB hard drive takes about fifteen minutes to create. Sparsely-allocated virtual disks take less time to create than do preallocated virtual disks.
If the deletion fails, fix the underlying problem for example, a failed host, an inaccessible storage device, or a temporary network issue and try again. First, you select one of the cluster hosts and a device type. Then, you choose and attach one or more of the host devices on that host. When you change the Pinned Host setting, it removes the current host devices.
When you finish attaching one or more host devices, you run the virtual machine to apply the changes. The virtual machine starts on the host that has the attached host devices. If the virtual machine cannot start on the specified host or access the host device, it cancels the start operation and produces an error message with information about the cause. The nvdimm option is a technical preview feature.
For more information, see nvdimm host devices. Click OK to attach these devices to the virtual machine and close the window. Click the Edit button. This opens the Edit Virtual Machine pane. In most cases, select scsi-hd. While the virtual machine starts running, watch for Operation Canceled error messages.
If you cannot add a host device to a virtual machine, or a virtual machine cannot start running with the attached host devices, it generates Operation Canceled error messages. For example:. You can fix the error by removing the host device from the virtual machine or correcting the issues the error message describes. Respond to a Cannot add Host devices because the VM is in Up status message by shutting down the virtual machine before adding a host device.
Pinning a Virtual Machine to Multiple Hosts. If you are removing all host devices directly attached to the virtual machine in order to add devices from a different host, you can instead add the devices from the desired host, which will automatically remove all of the devices already attached to the virtual machine. Click the Host Devices tab to list the host devices attached to the virtual machine.
Select the host device to detach from the virtual machine, or hold Ctrl to select multiple devices, and click Remove device. This opens the Remove Host Device s window. You can use the Host Devices tab in the details view of a virtual machine to pin it to a specific host. If the virtual machine has any host devices attached to it, pinning it to another host automatically removes the host devices from the virtual machine. Click Pin to another host. This opens the Pin VM to Host window.
Technology Preview features are not supported with Red Hat production service-level agreements SLAs and might not be functionally complete, and Red Hat does not recommend using them for production.
These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process. Precise sizing is also needed to make memory hotplug work. If those internal arrangements change, it can cause data loss. This combination is currently not expected to be stable until further work is completed.
Affinity groups help you determine where selected virtual machines run in relation to each other and specified hosts. This capability helps manage workload scenarios such as licensing requirements, high-availability workloads, and disaster recovery. When you create an affinity group, you select the virtual machines that belong to the group.
To define where these virtual machines can run in relation to each other , you enable a VM Affinity Rule : A positive rule tries to run the virtual machines together on a single host; a negative affinity rule tries to run the virtual machines apart on separate hosts.
If the rule cannot be fulfilled, the outcome depends on whether the weight or filter module is enabled. Optionally, you can add hosts to the affinity group. To define where virtual machines in the group can run in relation to hosts in the group , you enable a Host Affinity Rule : A positive rule tries to run the virtual machines on hosts in the affinity group; a negative affinity rule tries to run the virtual machines on hosts that are not in the affinity group.
With the weight module, the scheduler attempts to fulfill a rule, but allows the virtual machines in the affinity group to run anyway if the rule cannot be fulfilled. However, if a single host does not have sufficient resources for this, the scheduler runs the virtual machines on multiple hosts.
The filter module overrides the weight module. With the filter module enabled, the scheduler requires that a rule be fulfilled. If a rule cannot be fulfilled, the filter module prevents the virtual machines in the affinity group from running.
However, if those hosts are down, the scheduler does not run the virtual machines at all. To see how these rules and options can be used with one another, see Affinity group examples. An affinity label is functionally the same as an affinity group with a positive Host Affinity Rule and Enforcing enabled.
For affinity labels to work, the filter module section of the scheduling policies must contain Label. If an affinity group and affinity label conflict with each other, the affected virtual machines do not run. To help prevent, troubleshoot, and resolve conflicts, see Affinity group troubleshooting. For more information, see Scheduling Policies in the Administration Guide.
Affinity groups apply to virtual machines in a cluster. Moving a virtual machine from one cluster to another removes it from the affinity groups in the original cluster.
From the VM Affinity Rule drop-down, select Positive to apply positive affinity or Negative to apply negative affinity. Select Disable to disable the affinity rule. Select the Enforcing check box to apply hard enforcement, or ensure this check box is cleared to apply soft enforcement. Use the drop-down list to select the virtual machines to be added to the affinity group.
The affinity policy that applied to the virtual machines that were members of that affinity group no longer applies. The following examples illustrate how to apply affinity rules for various scenarios, using the different features of the affinity group capability described in this chapter. Dalia is the DevOps engineer for a startup.
Adds the two virtual machines, VM01 and VM02 , to the affinity group. Sets VM Affinity to Negative so the virtual machines try to run on separate hosts. Leaves Enforcing cleared disabled so that both virtual machines can continue running in case only one host is available during an outage.
Leaves the Hosts list empty so the virtual machines run on any host in the cluster. Sohni is a software developer who uses two virtual machines to build and test his software many times each day.
There is heavy network traffic between these two virtual machines. Running the machines on the same host reduces both network traffic and the effects of network latency on the build and test process.
Adds VM01 and VM02 , the build and test virtual machines, to the affinity group. Adds the high-specification hosts, host03 , host04 , and host05 , to the affinity group. Sets VM affinity to Positive so the virtual machines try to run on the same host, reducing network traffic and latency effects. Sets Host affinity to Positive so the virtual machines try to run on the high specification hosts, accelerating the process. Leaves Enforcing cleared disabled for both rules so the virtual machines can run if the high-specification hosts are not available.
Bandile, a software asset manager, helps his organization comply with the restrictive licensing requirements of a 3D imaging software vendor.
Additionally, the physical CPU-based licensing model requires that the workstations run on either of two GPU-equipped hosts, host-gpu-primary or host-gpu-backup. To meet these requirements, Bandile creates an affinity group called “3D seismic imaging” and does the following:. Sets VM affinity to Positive and selects Enforcing so the licensing server and workstations must run together on one of the hosts, not on multiple hosts.
Sets Host affinity to Positive and selects Enforcing so the virtual machines must run on either of the GPU-equipped the hosts, not other hosts in the cluster. Understand that an affinity label is the equivalent of an affinity group with a Host affinity rule that is Positive and has Enforcing enabled. Understand that if an affinity label and affinity group conflict with each other, the intersecting set of virtual machines do not run. Otherwise, a conflict is not possible.
Inspect the affinity groups. They must contain a rule that has Enforcing enabled. Inspect the affinity labels and groups. Make a list of virtual machines that are members of both an affinity label and an affinity group with an Enforcing option enabled. For each host and virtual machine in this intersecting set, analyze the conditions under which a potential conflict occurs.
If you have overlapping affinity groups and affinity labels, it can be easier to view them in one place as affinity groups. Consider converting an affinity label into an equivalent affinity group, which has a Host affinity rule with Positive selected and Enforcing enabled. Affinity labels are used to set hard Enforced positive affinity between virtual machines and hosts.
See the Affinity Groups section for more information about affinity hardness and polarity. Labels function identically to a hard positive affinity group, but simplify configuration in certain use cases. For example, if you have virtual machines that require specific host hardware, you can use affinity labels to ensure that those virtual machines run on the required hosts. If you use software that is license-limited to a certain number of physical machines, you can use affinity labels to ensure that virtual machines running that software are limited to the required physical hosts.
Affinity labels are a subset of affinity groups and can conflict with them. If there is a conflict, the virtual machine will not start. You can create affinity labels from the details view of a virtual machine, host, or cluster. This procedure uses the cluster details view. Click Compute Clusters and select the appropriate cluster. Use the drop-down lists to select the virtual machines and hosts to be associated with the label.
You can edit affinity labels from the details view of a virtual machine, host, or cluster. The export storage domain is deprecated. Storage data domains can be unattached from a data center and imported to another data center in the same environment, or in a different environment. Virtual machines, floating virtual disks, and templates can then be uploaded from the imported storage domain to the attached data center. You can export virtual machines and templates from, and import them to, data centers in the same or different Red Hat Virtualization environment.
You can export or import virtual machines by using an export domain, a data domain, or by using a Red Hat Virtualization host. When you export or import a virtual machine or template, properties including basic details such as the name and description, resource allocation, and high availability settings of that virtual machine or template are preserved. The permissions and user roles of virtual machines and templates are included in the OVF files, so that when a storage domain is detached from one data center and attached to another, the virtual machines and templates can be imported with their original permissions and user roles.
In order for permissions to be registered successfully, the users and roles related to the permissions of the virtual machines or templates must exist in the data center before the registration process. V2V converts virtual machines so that they can be hosted by oVirt. Export a virtual machine to the export domain so that it can be imported into a different data center. Before you begin, the export domain must be attached to the data center that contains the virtual machine to be exported.
Optionally, select the following check boxes in the Export Virtual Machine window:. Force Override : overrides existing images of the virtual machine on the export domain.
Collapse Snapshots : creates a single export volume per disk. This option removes snapshot restore points and includes the template in a template-based virtual machine, and removes any dependencies a virtual machine has on a template.
For a virtual machine that is dependent on a template, either select this option, export the template with the virtual machine, or make sure the template exists in the destination data center. When you create a virtual machine from a template by clicking Compute Templates and clicking New VM , you wll see two storage allocation options in the Storage Allocation section in the Resource Allocation tab:. If Clone is selected, the virtual machine is not dependent on the template.
The template does not have to exist in the destination data center. If Thin is selected, the virtual machine is dependent on the template, so the template must exist in the destination data center or be exported with the virtual machine.
Alternatively, select the Collapse Snapshots check box to collapse the template disk and virtual disk into a single disk. The export of the virtual machine begins. The virtual machine displays in Compute Virtual Machines with an Image Locked status while it is exported.
Depending on the size of your virtual machine hard disk images, and your storage hardware, this can take up to an hour. Click the Events tab to view progress. You can export a virtual machine to a data domain to store a clone of the virtual machine as a backup. When you export a virtual machine that is dependent on a template, the target storage domain should include that template.
When you create a virtual machine from a template, you can choose from either of two storage allocation options:. Clone : The virtual machine is not dependent on the template. The template does not have to exist in the destination storage domain. Thin : The virtual machine is dependent on the template, so the template must exist in the destination storage domain.
Optional Check Collapse snapshots to export the virtual machine without any snapshots. When you move a disk from one type of data domain another, the disk format changes accordingly.
For example, if the disk is on an NFS data domain, and it is in sparse format, then if you move the disk to an iSCSI domain its format changes to preallocated. This is different from using an export domain, because an export domain is NFS. The virtual machine appears with an Image Locked status while it is exported.
When complete, the virtual machine has been exported to the data domain and appears in the list of virtual machines. You have a virtual machine on an export domain. Before the virtual machine can be imported to a new data center, the export domain must be attached to the destination data center.
Click Storage Domains and select the export domain. The export domain must have a status of Active. Select the Collapse Snapshots check box to remove snapshot restore points and include templates in template-based virtual machines. Click the virtual machine to be imported and click the Disks sub-tab. From this tab, you can use the Allocation Policy and Storage Domain drop-down lists to select whether the disk used by the virtual machine will be thinly provisioned or preallocated, and can also select the storage domain on which the disk will be stored.
An icon is also displayed to indicate which of the disks to be imported acts as the boot disk for that virtual machine. The Import Virtual Machine Conflict window opens if the virtual machine exists in the virtualized environment. Import as cloned and enter a unique name for the virtual machine in the New Name field. Optionally select the Apply to all check box to import all duplicated virtual machines with the same suffix, and then enter a suffix in the Suffix to add to the cloned VMs field.
During a single import operation, you can only import virtual machines that share the same architecture. If any of the virtual machines to be imported have a different architecture to that of the other virtual machines to be imported, a warning will display and you will be prompted to change your selection so that only virtual machines with the same architecture will be imported.
If you are importing a virtual machine from an imported data storage domain, the imported storage domain must be attached to a data center and activated. For each virtual machine in the Import Virtual Machine s window, ensure the correct target cluster is selected in the Cluster list.
Map external virtual machine vNIC profiles to profiles that are present on the target cluster s :. If multiple target clusters are selected in the Import Virtual Machine s window, select each target cluster in the Target Cluster drop-down list and ensure the mappings are correct. If a MAC address conflict is detected, an exclamation mark appears next to the name of the virtual machine. Mouse over the icon to view a tooltip displaying the type of error that occurred.
Alternatively, you can select the Reassign check box per virtual machine. If there are no available addresses to assign, the import operation will fail. The imported virtual machines no longer appear in the list under the VM Import tab. Import virtual machines from a VMware vCenter provider to your oVirt environment. You can import from a VMware provider by entering its details in the Import Virtual Machine s window during each import operation, or you can add the VMware provider as an external provider, and select the preconfigured provider during import operations.
The virt-v2v package is not available on the ppc64le architecture and these hosts cannot be used as proxy hosts. The virt-v2v package must be installed on at least one host, referred to in this procedure as the proxy host. Local storage is not supported. This image includes the guest tools that are required for migrating Windows virtual machines. The virtual machine must be shut down before being imported. Starting the virtual machine through VMware during the import process can result in data corruption.
An import operation can only include virtual machines that share the same architecture. If any virtual machine to be imported has a different architecture, a warning appears and you are prompted to change your selection to include only virtual machines with the same architecture. Click More Actions and select Import. This opens the Import Virtual Machine s window. If you have configured a VMware provider as an external provider, select it from the External Provider list.
Verify that the provider credentials are correct. If you did not specify a destination data center or proxy host when configuring the external provider, select those options now. If you have not configured a VMware provider, or want to import from a new VMware provider, provide the following details:.
Select from the list the Data Center in which the virtual machine will be available. Enter the IP address or fully qualified domain name of the host from which the virtual machines will be imported in the ESXi field. Enter the name of the data center and the cluster in which the specified ESXi host resides in the Data Center field. If not, clear the option. The user must have access to the VMware data center and ESXi host on which the virtual machines reside.
Select a host in the chosen data center with virt-v2v installed to serve as the Proxy Host during virtual machine import operations. This host must also be able to connect to the network of the VMware vCenter external provider. Click Load to list the virtual machines on the VMware provider that can be imported. Select one or more virtual machines from the Virtual Machines on Source list, and use the arrows to move them to the Virtual Machines to Import list.
Click Next. If required, you can change the driver type to VirtIO manually after the import. To change the driver type after a virtual machine has been imported, see Editing network interfaces.
If the network device uses driver types other than e or rtl, the driver type is changed to VirtIO automatically during the import. The Attach VirtIO-drivers option allows the VirtIO drivers to be injected to the imported virtual machine files so that when the driver is changed to VirtIO, the device will be properly detected by the operating system.
Select the Clone check box to change the virtual machine name and MAC addresses, and clone all disks, removing all snapshots. If a virtual machine appears with a warning symbol beside its name or has a tick in the VM in System column, you must clone the virtual machine and change its name. Click each virtual machine to be imported and click the Disks sub-tab. Use the Allocation Policy and Storage Domain lists to select whether the disk used by the virtual machine will be thinly provisioned or preallocated, and select the storage domain on which the disk will be stored.
If you selected the Clone check box, change the name of the virtual machine in the General sub-tab. Click Compute Clusters. You can export a virtual machine to a specific path or mounted NFS shared storage on a host in the oVirt data center. Enter the absolute path to the export directory in the Directory field, including the trailing slash.
You can import the file from any oVirt Node in the data center. The import process uses virt-v2v. Only virtual machines running operating systems compatible with virt-v2v can be successfully imported. Ensure that it has sufficient space. Select the virtual machine from the Virtual Machines on Source list, and use the arrows to move it to the Virtual Machines to Import list.
Select the virtual machine, and on the General tab select the Operating System. Import virtual machines from Xen on Enterprise Linux 5 to your oVirt environment. The virt-v2v package must be installed on at least one host referred to in this procedure as the proxy host. Enterprise Linux hosts must be Enterprise Linux 7. If the drivers are not installed, the virtual machine may not boot after import. If you are not using VirtIO drivers, review the configuration of the virutal machine before first boot to ensure that VirtIO devices are not being used.
Shut down the virtual machine. Starting the virtual machine through Xen during the import process can result in data corruption. Due to current limitations, Xen virtual machines with block devices do not appear in the Virtual Machines on Source list.
They must be imported manually. The target storage domain must be a file-based domain. Due to current limitations, specifying a block-based domain causes the V2V operation to fail. If a virtual machine appears with a warning symbol beside its name, or has a tick in the VM in System column, select the Clone check box to clone the virtual machine.
Cloning a virtual machine changes its name and MAC addresses and clones all of its disks, removing all snapshots. Attach an export domain. Import the virtual machine into the destination data domain.
See Importing the virtual machine from the export domain for details. Import virtual machines from KVM to your oVirt environment. You must enable public key authentication between the KVM host and at least one host in the destination data center this host is referred to in the following procedure as the proxy host. Starting the virtual machine through KVM during the import process can result in data corruption. Optionally, select the Collapse Snapshots check box to remove snapshot restore points and include templates in template-based virtual machines.
Optionally, select the Clone check box to change the virtual machine name and MAC addresses, and clone all disks, removing all snapshots. Use the Allocation Policy and Storage Domain lists to select whether the disk used by the virtual machine will be thin provisioned or preallocated, and select the storage domain on which the disk will be stored.
If you selected the Clone check box, change the name of the virtual machine in the General tab. This image is a virtual machine snapshot with a preconfigured instance of Enterprise Linux installed. You can configure this image with the cloud-init tool, and use it to provision new virtual machines.
This eliminates the need to install and configure the operating system and provides virtual machines that are ready for use. Create a new virtual machine and attach the uploaded disk image to it. See Creating a Linux virtual machine. Optionally, use cloud-init to configure the virtual machine. Optionally, create a template from the virtual machine.
You can generate new virtual machines from this template. See Templates for information about creating templates and generating virtual machines from templates. Live migration provides the ability to move a running virtual machine between physical hosts with no interruption to service.
The virtual machine remains powered on and user applications continue to run while the virtual machine is relocated to a new physical host. Storage and network connectivity are not altered. You can use live migration to seamlessly move virtual machines to support a number of common maintenance tasks. Your oVirt environment must be correctly configured to support live migration well in advance of using it. At a minimum, the following prerequisites must be met to enable successful live migration of virtual machines:.
The source and destination hosts are members of the same cluster, ensuring CPU compatibility between them. The source and destination hosts have access to the data storage domain on which the virtual machine resides. Live migration is performed using the management network and involves transferring large amounts of data between hosts.
Concurrent migrations have the potential to saturate the management network. For best performance, create separate logical networks for management, storage, display, and virtual machine data to minimize the risk of network saturation. Add both vNICs as slaves under an active-backup bond on the virtual machine, with the passthrough vNIC as the primary interface.
The following steps are provided only as a Technology Preview. Hotplug a network interface with the failover vNIC profile you created into the virtual machine, or start a virtual machine with this network interface plugged in. The virtual machine has three network interfaces: a controller interface and two secondary interfaces. The controller interface must be active and connected in order for migration to succeed.
For automatic deployment of virtual machines with this configuration, use the following udev rule:. This udev rule works only on systems that manage interfaces with NetworkManager. This rule ensures that only the controller interface is activated. Live virtual machine migration can be a resource-intensive operation. To optimize live migration, you can set the following two options globally for every virtual machine in an environment, for every virtual machine in a cluster, or for an individual virtual machine.
The Auto Converge migrations and Enable migration compression options are available for cluster levels 4. For cluster levels 4. You can change these parameters when adding a new migration policy, or by modifying the MigrationPolicies configuration value.
The Auto Converge migrations option allows you to set whether auto-convergence is used during live migration of virtual machines. Large virtual machines with high workloads can dirty memory more quickly than the transfer rate achieved during live migration, and prevent the migration from converging.
Auto-convergence capabilities in QEMU allow you to force convergence of virtual machine migrations. The Enable migration compression option allows you to set whether migration compression is used during live migration of the virtual machine. This feature uses Xor Binary Zero Run-Length-Encoding to reduce virtual machine downtime and total live migration time for virtual machines running memory write-intensive workloads or for any application with a sparse memory update pattern.
Click Compute Clusters and select a cluster. All files or symbolic links in that directory will be executed. The executing user on Linux systems is ovirtagent. If the script needs root permissions, the elevation must be executed by the creator of the hook script. The destination host for each virtual machine is assessed as the virtual machine is migrated, in order to spread the load across the cluster. From version 4. The Engine automatically initiates live migration of virtual machines in order to maintain load-balancing or power-saving levels in line with scheduling policy.
Specify the scheduling policy that best suits the needs of your environment. You can also disable automatic, or even manual, live migration of specific virtual machines where required. However, this can be changed to Allow Manual and Automatic mode if required.
Special care should be taken when changing the default migration setting so that it does not result in a virtual machine migrating to a host that does not support high performance or pinning. You can also disable manual migration of virtual machines by setting the virtual machine to run only on a specific host.
The ability to disable automatic migration and require a virtual machine to run on a particular host is useful when using application high availability products, such as Red Hat High Availability or Cluster Suite.
Explicitly assigning a virtual machine to a specific host and disabling migration are mutually exclusive with oVirt high availability. If the virtual machine has host devices directly attached to it, and a different host is specified, the host devices from the previous host will be automatically removed from the virtual machine.
Select Allow manual migration only or Do not allow migration from the Migration Options drop-down list.
