Subject: Re: [patch 0/3] fix PIT injection

Hi Marcelo:

With kvm-72 + this patch set, timekeeping in RHEL3, RHEL4 and RHEL5
guests with 2 vcpus is much better. Approaching 5 hours of uptime and
all 3 guests are within 2 seconds of the host (part of the delta
measurement based). I'll let all 3 run overnight and then turn on ntp
tomorrow.

Thanks for working on this,

david
