9.19.3.2.2. Configuring disk sharing by using LUN and the CLI

Procedure

1. Edit or create the VirtualMachine manifest for your VM to set the required values, as shown in the following example:

   apiVersion: kubevirt.io/v1
   kind: VirtualMachine
   metadata:
     name: vm-0
   spec:
     template:
       spec:
         domain:
           devices:
             disks:
             - disk:
                 bus: sata
               name: rootdisk
             - errorPolicy: report
               lun:
                 bus: scsi
                 reservation: true
               name: na-shared
               serial: shared1234
         volumes:
         - dataVolume:
             name: vm-0
           name: rootdisk
         - name: na-shared
           persistentVolumeClaim:
             claimName: pvc-na-share

   • spec.template.spec.domain.devices.disks.errorPolicy defines how the hypervisor should behave when an IO error occurs.
   • spec.template.spec.domain.devices.disks.lun defines a volume exposed as a LUN device.
   • spec.template.spec.domain.devices.disks.lun.reservation defines whether the persistent reservation is enabled.
2. Save the VirtualMachine manifest file to apply your changes.
