I first checked the related known fixes from the old case that is linked. Just in case if we might miss one in Ubuntu 20.04 that you are using.

Even after forcing them off via virsh, and restarting them the guests are paused. These Guests are not nested. A lot of diganostic information are outlined in the previous bug report link provided. The solution mentioned in previous report had been allegedly integrated into the downstream updates.
