[CentOS] 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.
