I'm guessing there's a problem with timers or timer interrupts.

What is the host cpu?

4 entries like this in /proc/cpuinfo:

processor       : 3
vendor_id       : AuthenticAMD
cpu family      : 15
model           : 65
model name      : Dual-Core AMD Opteron(tm) Processor 2212


That's probably the kvmclock issue that hit older AMDs. It was fixed in kvm-84, please try that.

It is kvm-84, I have it running since Saturday (but I had this issue with kvm-83 as well).


And the problem continues?

What's your current clocksource (in the guest)?  Does changing it help?

See /sys/devices/system/clocksource/clocksource0/*.


I meant 'taskset 01 qemu ...' but it wouldn't have helped if it's kvmclock.

It can be done on a running process as well (22906 is the PID of the affected gue

Right, but if the guest is poisoned somehow, this won't help.
