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.
