I have no idea what is causing it. Fedora 12 and Centos 5.5 KVM machines run fine on the same host. Is there any debugging I can enable to see what is jumping the clock? kvm-clock: cpu 0, msr 0:1ba4741, boot clock kvm-clock: cpu 0, msr 0:1e15741, primary cpu clock Switching to clocksource kvm-clock rtc_cmos 00:01: setting system clock to 2010-05-20 16:59:48 UTC (1274374788) Thanks, Orion
