10.12.2. Setting the VM interface link state by using the CLI

Procedure

1. Edit the VM configuration to set the interface link state, as in the following example:

   apiVersion: kubevirt.io/v1
   kind: VirtualMachine
   metadata:
     name: my-vm
   spec:
     template:
       spec:
         domain:
           devices:
             interfaces:
               - name: default
                 state: down
                 masquerade: { }
         networks:
           - name: default
             pod: { }
   # ...

   • spec.template.spec.domain.devices.interfaces.name defines the name of the interface.

   • spec.template.spec.domain.devices.interfaces.state defines the state of the interface. The possible values are:

     • up: Represents an active network connection. This is the default if no value is specified.
     • down: Represents a network interface link that is switched off.

     • absent: Represents a network interface that is hot unplugged.

       중요

       If you have defined readiness or liveness probes to run VM health checks, setting the primary interface’s link state to down causes the probes to fail. If a liveness probe fails, the VM is deleted and a new VM is created to restore responsiveness.

2. Apply the VirtualMachine manifest:

   $ oc apply -f <filename>.yaml
