In fact, related - on our systems attempt to start qemu-kvm VM under kernel-3.10.0-1160.80.1.el7.x86_64 freezes any of 5 workstations with dual E5507 (all worked OK under kernel-3.10.0-1160.76.1.el7.x86_64 and any previous version). The workstations with E5-2609, E5-2650 or E5-2630 are not affected - all of them run qemu-kvm VM under kernel-3.10.0-1160.80.1.el7.x86_64 without problems.
Any ideas?

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.
