[libvirt] guest clock offset, configuration

Hi, I'm having some trouble with guests booting up with huge clock offset (4 hrs). The offset is always the same which leads me to suspecting a configuration issue rather than a bug. I looked around libvirt documentation and so far checked these: * the hosts clock is correct (ntpd, manually verified) * the timezones are correct (and the same) on both host and guest * the clock element in the guest xml seems to be correct for a Linux guest - "<clock offset='utc'/>" Is there anything else I should check? FWIW, hosts are Fedora 12, guests are a mix of recent Fedoras. Thanks for any pointers, Jakub
