No such luck here; I've just tried an amd64 machine (8-STABLE from today) in a new installation of XenServer 5.6 and while the GENERIC kernel works stable enough, the XENHVM kernel produces all kinds of timer-related problems, accompanied by messages like: Feb 18 23:20:03 xbsd kernel: calcru: runtime went backwards from 28669021884109 usec to 22622950 usec for pid 11 (idle) The difference between 28669021884109 and 22622950 is huge! It almost looks like a memory corruption. ___ 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

Ensure you add the correct device to /etc/rc.conf afterwards, I believe it changes to xn0 when running XENHVM.
