Use one of these procedures to create a virtual machine:

  • Quick Start guided tour

  • Quick create from the Catalog

  • Pasting a pre-configured YAML file with the virtual machine wizard

  • Using the CLI

Do not create virtual machines in openshift-* namespaces. Instead, create a new namespace or use an existing namespace without the openshift prefix.

When you create virtual machines from the web console, select a virtual machine template that is configured with a boot source. Virtual machine templates with a boot source are labeled as Available boot source or they display a customized label text. Using templates with an available boot source expedites the process of creating virtual machines.

Templates without a boot source are labeled as Boot source required. You can use these templates if you complete the steps for adding a boot source to the virtual machine.

Due to differences in storage behavior, some virtual machine templates are incompatible with single-node OpenShift. To ensure compatibility, do not set the evictionStrategy field for any templates or virtual machines that use data volumes or storage profiles.

Using a Quick Start to create a virtual machine

The web console provides Quick Starts with instructional guided tours for creating virtual machines. You can access the Quick Starts catalog by selecting the Help menu in the Administrator perspective to view the Quick Starts catalog. When you click on a Quick Start tile and begin the tour, the system guides you through the process.

Tasks in a Quick Start begin with selecting a Red Hat template. Then, you can add a boot source and import the operating system image. Finally, you can save the custom template and use it to create a virtual machine.

  • Access to the website where you can download the URL link for the operating system image.

  1. In the web console, select Quick Starts from the Help menu.

  2. Click on a tile in the Quick Starts catalog. For example: Creating a Red Hat Linux Enterprise Linux virtual machine.

  3. Follow the instructions in the guided tour and complete the tasks for importing an operating system image and creating a virtual machine. The VirtualizationVirtualMachines page displays the virtual machine.

Quick creating a virtual machine

You can quickly create a virtual machine (VM) by using a template with an available boot source.

  1. Click VirtualizationCatalog in the side menu.

  2. Click Boot source available to filter templates with boot sources.

    By default, the template list will show only Default Templates. Click All Items when filtering to see all available templates for your chosen filters.

  3. Click a template to view its details.

  4. Click Quick Create VirtualMachine to create a VM from the template.

    The virtual machine Details page is displayed with the provisioning status.

  1. Click Events to view a stream of events as the VM is provisioned.

  2. Click Console to verify that the VM booted successfully.

Creating a virtual machine from a customized template

Some templates require additional parameters, for example, a PVC with a boot source. You can customize select parameters of a template to create a virtual machine (VM).

  1. In the web console, select a template:

    1. Click VirtualizationCatalog in the side menu.

    2. Optional: Filter the templates by project, keyword, operating system, or workload profile.

    3. Click the template that you want to customize.

  2. Click Customize VirtualMachine.

  3. Specify parameters for your VM, including its Name and Disk source. You can optionally specify a data source to clone.

  1. Click Events to view a stream of events as the VM is provisioned.

  2. Click Console to verify that the VM booted successfully.

Refer to the virtual machine fields section when creating a VM from the web console.

Virtual machine fields

The following table lists the virtual machine fields that you can edit in the OpenShift Container Platform web console:

Table 1. Virtual machine fields
Tab Fields or functionality


  • Description

  • CPU/Memory

  • Boot mode

  • GPU devices

  • Host devices


  • View, edit, or download the custom resource.


  • Node selector

  • Tolerations

  • Affinity rules

  • Dedicated resources

  • Eviction strategy

  • Descheduler setting


  • Add, edit, or delete a config map, secret, or service account.

Network Interfaces

  • Add, edit, or delete a network interface.


  • Add, edit, or delete a disk.


  • cloud-init settings

  • Authorized SSH key

  • Sysprep answer files


  • Labels

  • Annotations

Networking fields

Name Description


Name for the network interface controller.


Indicates the model of the network interface controller. Supported values are e1000e and virtio.


List of available network attachment definitions.


List of available binding methods. Select the binding method suitable for the network interface:

  • Default pod network: masquerade

  • Linux bridge network: bridge

  • SR-IOV network: SR-IOV

MAC Address

MAC address for the network interface controller. If a MAC address is not specified, one is assigned automatically.

Storage fields

Name Selection Description


Blank (creates PVC)

Create an empty disk.

Import via URL (creates PVC)

Import content via URL (HTTP or HTTPS endpoint).

Use an existing PVC

Use a PVC that is already available in the cluster.

Clone existing PVC (creates PVC)

Select an existing PVC available in the cluster and clone it.

Import via Registry (creates PVC)

Import content via container registry.

Container (ephemeral)

Upload content from a container located in a registry accessible from the cluster. The container disk should be used only for read-only filesystems such as CD-ROMs or temporary virtual machines.


Name of the disk. The name can contain lowercase letters (a-z), numbers (0-9), hyphens (-), and periods (.), up to a maximum of 253 characters. The first and last characters must be alphanumeric. The name must not contain uppercase letters, spaces, or special characters.


Size of the disk in GiB.


Type of disk. Example: Disk or CD-ROM


Type of disk device. Supported interfaces are virtIO, SATA, and SCSI.

Storage Class

The storage class that is used to create the disk.

Advanced storage settings

The following advanced storage settings are optional and available for Blank, Import via URL, and Clone existing PVC disks. Before OpenShift Virtualization 4.11, if you do not specify these parameters, the system uses the default values from the kubevirt-storage-class-defaults config map. In OpenShift Virtualization 4.11 and later, the system uses the default values from the storage profile.

Use storage profiles to ensure consistent advanced storage settings when provisioning storage for OpenShift Virtualization.

To manually specify Volume Mode and Access Mode, you must clear the Apply optimized StorageProfile settings checkbox, which is selected by default.

Name Mode description Parameter Parameter description

Volume Mode

Defines whether the persistent volume uses a formatted file system or raw block state. Default is Filesystem.


Stores the virtual disk on a file system-based volume.


Stores the virtual disk directly on the block volume. Only use Block if the underlying storage supports it.

Access Mode

Access mode of the persistent volume.

ReadWriteOnce (RWO)

Volume can be mounted as read-write by a single node.

ReadWriteMany (RWX)

Volume can be mounted as read-write by many nodes at one time.

This is required for some features, such as live migration of virtual machines between nodes.

ReadOnlyMany (ROX)

Volume can be mounted as read only by many nodes.

Cloud-init fields

Name Description


Sets a specific hostname for the virtual machine.

Authorized SSH Keys

The user’s public key that is copied to ~/.ssh/authorized_keys on the virtual machine.

Custom script

Replaces other options with a field in which you paste a custom cloud-init script.

To configure storage class defaults, use storage profiles. For more information, see Customizing the storage profile.

Pasting in a pre-configured YAML file to create a virtual machine

Create a virtual machine by writing or pasting a YAML configuration file. A valid example virtual machine configuration is provided by default whenever you open the YAML edit screen.

If your YAML configuration is invalid when you click Create, an error message indicates the parameter in which the error occurs. Only one error is shown at a time.

Navigating away from the YAML screen while editing cancels any changes to the configuration you have made.

  1. Click VirtualizationVirtualMachines from the side menu.

  2. Click Create and select With YAML.

  3. Write or paste your virtual machine configuration in the editable window.

    1. Alternatively, use the example virtual machine provided by default in the YAML screen.

  4. Optional: Click Download to download the YAML con
