Hi all, I have just upgraded ovirt manager from 4.1.0 to 4.1.1, then I have upgraded one host. After reboot and activation of this host some vms started to migrate here.
Some time after migration CPU of this vms go to 100% and vms become unreachable. There is /var/log/libvirt/qemu/hypnos.log (hypnos is one of this vms) https://pastebin.com/U30xfBMJ Powering off and starting again solve this but I would like to have a glue what is happening. I suspect this line 2017-03-27T22:09:23.746710Z qemu-kvm: warning: TSC frequency mismatch between VM (2600031 kHz) and host (2100024 kHz), and TSC scaling unavailable Original host uses "AMD Opteron(TM) Processor 6238" with "cpu MHz: 2600.113" and upgraded host uses "AMD Opteron(tm) Processor 6172" with "cpu MHz: 2100.097". Cheers, Jiri
