On the other hand ---  I just upgraded one of my CentOS7 systems to 
3.10.0-1160.80.1 today.  With that kernel it will not run any KVM guest. 
  The system hangs - HARD - within one or two seconds of issuing the 
"virsh start ..." command.  It hangs so hard that a power-off restart 
using the back panel switch is required.  It does not log any error I 
can find, nor display any message about a kernel panic.

Rebooting with 3.10.0-1160.76.1 works fine.

The system is an older SuperMicro mainboard with a Q9400 processor.
