Subject: Timedrift in KVM guests after livemigration.
Date: Thu, 15 Apr 2010 09:35:13 +0200 [thread overview]
Message-ID: <4BC6C1B1.5010206@monsternett.no> (raw)
We have three KVM hosts that supports live-migration between them, but
one of our problems is time drifting. The three frontends has different
CPU frequency and the KVM guests adopt the frequency from the host
machine where it was first started.
Host1: cat /proc/cpuinfo
model name : Intel(R) Core(TM)2 CPU 6600 @ 2.40GHz
cpu MHz : 2394.048
Host2: cat /proc/cpuinfo
model name : Intel(R) Core(TM)2 CPU 6700 @ 2.66GHz
cpu MHz : 2659.685
Host3: cat /proc/cpuinfo
model name : Intel(R) Xeon(R) CPU E5410 @ 2.33GHz
cpu MHz : 2327.507
virsh version
Compiled against library: libvir 0.7.6
Using library: libvir 0.7.6
Using API: QEMU 0.7.6
Running hypervisor: QEMU 0.11.0
Is there any solution to our problems, or is a reboot the only safe
solution?
Regards
Espen
