8.3. Creating VMs 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 

   1

   
   spec:
     dataVolumeTemplates:
     - metadata:
         name: imported-volume-mk4lj
       spec:
         sourceRef:
           kind: DataSource
           name: rhel9 

   2

   
           namespace: openshift-virtualization-os-images 

   3

   
         storage:
           resources: {}
     instancetype:
       inferFromVolume: imported-volume-mk4lj 

   4

   
       inferFromVolumeFailurePolicy: Ignore
     preference:
       inferFromVolume: imported-volume-mk4lj 

   5

   
       inferFromVolumeFailurePolicy: Ignore
     runStrategy: Always
     template:
       spec:
         domain:
           devices: {}
           memory:
             guest: 512Mi
           resources: {}
         terminationGracePeriodSeconds: 180
         volumes:
         - dataVolume:
             name: imported-volume-mk4lj
           name: imported-volume-mk4lj

   1

   The VM name.

   2

   The boot source for the guest operating system.

   3

   The namespace for the boot source. Golden images are stored in the openshift-virtualization-os-images namespace.

   4

   The instance type is inferred from the selected DataSource object.

   5

   The preference is inferred from the selected DataSource object.

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>
