Re: Clock drift issues
Try running ntpd rather than one off ntpdate? I have plenty of physical machines that need this anyway.

Re: Clock drift issues
Hi, The clock is Sync'd though, it should *stay* correct, right? So there is a bug? On Mon, 30 May 2011 09:39:06 +0100, Vincent Hoffman wrote: Try running ntpd rather than one off ntpdate?

My experience is also that the clock is not stable on FreeBSD 8.X guest on Xen and KVM HVM. It is unusable as a ntp server for other hosts and I need to run ntpd to prevent the guest clock from drifting and jumping. Some times I get syslog messages about the time going backwards, which is probably related: calcru: runtime went backwards from 41668 usec to 35093 usec for pid 96767 (bash) I have not tried this with the CURRENT kernel (which has new and configurable event timer infrastructure by mav@). (Linux guests are fine for running ntp server within Xen KVM.) -- Janne Snabb / EPIPE Communications sn...@epipe.com - http://epipe.com/ ___ freebsd-xen@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-xen To unsubscribe, send any mail to freebsd-xen-unsubscr...@freebsd.org
