Hi!
We have a problem with paused VMs in ovirt cluster. Please, help to solve this.
In ovirt manager massege "VM rtb-stagedsw02-ovh has been paused."
Resume fails with error "Failed to resume VM rtb-stagedsw02-ovh (Host: ovirt-node09-ovh.local, User: admin@internal-authz)."
In oVirt Cluster 38 VM, paused VM only ubuntu 20.04 focal with docker swarm.
Archived logs in attach.

KVM: entry failed, hardware error 0x80000021

If you're running a guest on an Intel machine without unrestricted mode
support, the failure can be most likely due to the guest entering an invalid
state for Intel VT. For example, the guest maybe running in big real mode
which is not supported on less recent Intel processors.
