Default KVM migration and time

Hi all,

I have two Cent5.6 systems running KVM in a clustered configuration with Cent5.6 guests.* Ntpd is running on both hosts and all guests.

When the guest is booted onto either of the hosts, time stays synced.* When I do a live migration to the other host, the time on the guest starts going haywire, fast-forwarding into the future at a steady rate.


After digging around, this may be related to: https://bugzilla.redhat.com/show_bug.cgi?id=513138

Can anyone tell me if there's a correct combination of guest kernel parameters and/or host settings that will fix this?


Thanks in advance.

...adam

Not an expert on this matter.

I would rather make one physical host sync against one external NTP
and point all the other hosts to this system.

YMMV
