Avi, I booted the guest with clocksource=acpi_pm and it has been running under heavy load for about 4 hours with kvm -smp 12. Considering that the guest previously would not even boot with kvm -smp 12, I think this is the root cause. As another data point, I was not able to trigger the bug when running a guest with all active cores on socket 0 only, but I was able to trigger it when putting half the cores on socket 1. So in a nutshell the kernel uses an unreliable clock source by default on SMP systems? Thanks for your help!
