Just to confirm the solution in this ticket. I had the same issue on Ubuntu 22.04. Hypervisor services kept becoming unreachable with a single problematic VM after a approximately 2 hours of runtime. Tried updates, firmware updates and all the good things.
Turns out Ubuntu hides new Kernel versions (version 6.x in my case) behind a Hardware Enablement package. I searched for too long to find the solution so I'm leaving breadcrumbs for the next person
