      Description of problem:

      The destination domain will be in paused status during virtual machine live migration. However, it looks like virt-launcher is continuously trying to set the guest time when the VM is paused and results in the below events every second.

      The error is expected from the libvirtd when the VM is paused:

      ~~~
      virsh -r list |grep -i nijin_test_2
      5 nijin_test_2 paused

      virsh domtime nijin_test_2 --now
      error: Requested operation is not valid: domain is not running
      ~~~

      Version-Release number of selected component (if applicable):

      kubevirt-hyperconverged-operator.v4.9.3

      How reproducible:

      100%

      Steps to Reproduce:

      1. Live migrate a virtual machine.
      2. Watch for the logs in the destination virt-launcher pod.

      Actual results:

      "failed to sync guest time" log spam in destination virt-launcher pod during VM live migration

      Expected results:

      These logs spam the destination virt-launcher pod and hence I think shouldn't be logged during the migration.
