8.6. Creating virtual machines by using the CLI

Procedure

1. Create a VirtualMachine manifest for your VM and save it as a YAML file. For example, to create a minimal Red Hat Enterprise Linux (RHEL) VM, run the following command:

   $ virtctl create vm --name rhel-9-minimal --volume-import type:ds,src:openshift-virtualization-os-images/rhel9

2. Review the VirtualMachine manifest for your VM:

   참고

   This example manifest does not configure VM authentication.

   Example manifest for a RHEL VM

   apiVersion: kubevirt.io/v1
   kind: VirtualMachine
   metadata:
     name: rhel-9-minimal
   spec:
     dataVolumeTemplates:
     - metadata:
         name: imported-volume-mk4lj
       spec:
         sourceRef:
           kind: DataSource
           name: rhel9
           namespace: openshift-virtualization-os-images
         storage:
           resources: {}
     instancetype:
       inferFromVolume: imported-volume-mk4lj
       inferFromVolumeFailurePolicy: Ignore
     preference:
       inferFromVolume: imported-volume-mk4lj
       inferFromVolumeFailurePolicy: Ignore
     runStrategy: Always
     template:
       spec:
         domain:
           devices:
             video:
               type: virtio
           memory:
             guest: 512Mi
           resources: {}
         terminationGracePeriodSeconds: 180
         volumes:
         - dataVolume:
             name: imported-volume-mk4lj
           name: imported-volume-mk4lj

   • name: rhel-9-minimal specifies the name of the VM.
   • name: rhel9 specifies the boot source for the guest operating system in the sourceRef section.
   • namespace: openshift-virtualization-os-images specifies the namespace for the boot source. Golden images are stored in the openshift-virtualization-os-images namespace.
   • instancetype: inferFromVolume: imported-volume-mk4lj specifies the instance type inferred from the selected DataSource object.
   • preference: inferFromVolume: imported-volume-mk4lj specifies that the preference is inferred from the selected DataSource object.
   • type: virtio specifies the use of a custom video device (a VirtIO device in this example) to enable hardware graphics acceleration. Enabling a custom video device is in Technology Preview for OpenShift Virtualization 4.21.

3. Create a virtual machine by using the manifest file:

   $ oc create -f <vm_manifest_file>.yaml

4. Optional: Start the virtual machine:

   $ virtctl start <vm_name>
