Creating virtual machines from the command line

You can create virtual machines (VMs) from the command line by editing or creating a VirtualMachine manifest.

Creating a VM from a VirtualMachine manifest

You can create a virtual machine (VM) from a VirtualMachine manifest.

Procedure

  1. Edit the VirtualMachine manifest for your VM. The following example configures a Fedora VM:

    Example manifest for a Fedora VM 
    apiVersion: kubevirt.io/v1
kind: VirtualMachine
metadata:
  labels:
    app: <vm_name> (1)
  name: <vm_name>
spec:
  dataVolumeTemplates:
  - apiVersion: cdi.kubevirt.io/v1beta1
    kind: DataVolume
    metadata:
      name: <vm_name>
    spec:
      sourceRef:
        kind: DataSource
        name: rhel9 (2)
        namespace: openshift-virtualization-os-images
      storage:
        resources:
          requests:
            storage: 30Gi
  running: false
  template:
    metadata:
      labels:
        kubevirt.io/domain: <vm_name>
    spec:
      domain:
        cpu:
          cores: 1
          sockets: 2
          threads: 1
        devices:
          disks:
          - disk:
              bus: virtio
            name: rootdisk
          - disk:
              bus: virtio
            name: cloudinitdisk
          interfaces:
          - masquerade: {}
            name: default
          rng: {}
        features:

            enabled: true
        firmware:
          bootloader:
            efi: {}
        resources:
          requests:
            memory: 8Gi
      evictionStrategy: LiveMigrate
      networks:
      - name: default
        pod: {}
      volumes:
      - dataVolume:
          name: <vm_name>
        name: rootdisk
      - cloudInitNoCloud:
          userData: |-
            #cloud-config
            user: cloud-user
            password: '<password>' (3)
            chpasswd: { expire: False }
        name: cloudinitdisk
    1 Specify the name of the virtual machine.
    2 Specify the name in the spec.dataImportCronTemplate.spec.managedDataSource field in the Hyperconvered CR.
    3 Specify the password for cloud-user.

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

    $ oc create -f <vm_manifest_file>.yaml

  3. Optional: Start the virtual machine:

    $ virtctl start <vm_name> -n <namespace>
