Description of problem:

Runstrategy of the VM is not changing ,when rebooting a VM (which is already running with the runstrategy as RerunOnFailure). But the runstrategy getting modified whenwe perform stop and start of the VM.

Environment : OCP- 4.12.18 CNV-4.12.5

How reproducible:

1.Created a VM with runstrategy as RerunOnFailure

1. oc get vmi

NAME AGE PHASE IP NODENAME READY
virtualmachineinstance.kubevirt.io/coreos 35d Running 10.130.1.6 openshift-master-regulus-2 True

1. oc get vm coreos -o yaml | grep -i strategy
   runStrategy: RerunOnFailure

Scenario 1 : After Reboot

1. oc get vmi

NAME AGE PHASE IP NODENAME READY
virtualmachineinstance.kubevirt.io/coreos 3m45s Running 10.130.1.150 openshift-master-regulus-2 True

1. oc get vm coreos -o yaml | grep -i strategy
   runStrategy: RerunOnFailure <<<
   No change in runStrategy

Scenario 2 : After Stop and start

Stopped the VM from GUI console

1. oc get vmi coreos; oc get vm coreos -o yaml | grep -i strategy
   Error from server (NotFound): virtualmachineinstances.kubevirt.io "coreos" not found
   runStrategy: Halted <<<<

Starting the VM from GUI console

1. oc get vmi coreos; oc get vm coreos -o yaml | grep -i strategy

NAME AGE PHASE IP NODENAME READY
coreos 24s Running 10.130.1.151 openshift-master-regulus-2 True

runStrategy: Always <<<<

Actual results:

VM spec.runStrategy setting got modified after VM Stop and start

Expected results: Persistent edit of VM spec.runStrategy setting after VM reboot
