Not able to enable restart button and disable pause button for a VM.

OCP 4.20.8
openshift-cnv 4.20.3

Easily

1. Create a VM from the default template like rhel 8 by a admin user in a new project(my-test). 
2. Create a new user(testRole) and give this user the default view clusterrole of the my-test project.
3. Create a custom role with the rules of kubevirt.io apigroups.

- The testRole user has 2 roles.
$ oc get rolebinding -o wide | grep testRole
kubevirt.io:testRole        Role/my-vm-role                         34m   testRole                                        
testRole-view               ClusterRole/view                        80m   testRole                                        
$ oc get clusterrolebinding -o wide | grep testRole
$ 

- When use following custom role, the stop, restart, pause, start buttons work as expected (NonDisable01.png, NonDisable02.png).

- but if you remove virtualmachineinstances/pause and virtualmachineinstances/unpause, the restart button will disappear (DisablePause_VMon.png). The role was deleted and recreated after the change.

      - virtualmachines/start
      - virtualmachines/stop
      - virtualmachines/restart
      #- virtualmachineinstances/pause
      #- virtualmachineinstances/unpause

- And if you remove virtualmachines/restart, the pause button will disappear(DisableRestart_VMon.png). The role was deleted and recreated after the change. Click the restart button, no respond(DisableRestart_click.png).

      - virtualmachines/start
      - virtualmachines/stop
      #- virtualmachines/restart
      - virtualmachineinstances/pause
      - virtualmachineinstances/unpause  

The actions of rules virtualmachines/restart and virtualmachineinstances/pause, virtualmachineinstances/unpause are reversed.

The actions of rules virtualmachines/restart and virtualmachineinstances/pause, virtualmachineinstances/unpause work as expected.
