[ovirt-users] vms stucked after migrate from 4.1.0 to 4.1.1 host

[Jiří Sléžka]

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
