Keeping time in guest domains

["Johnny C. Lam" <jlam%pkgsrc.org@localhost>]

What's the right way to keep the right time in guest domains?  I'm
running NetBSD-3.0_BETA on an old dual Xeon box.  I have ntpd running
in the privileged domain, but nothing time-related running in the
guest domains.  The dom0 clock is correct and stays correct, but the
domU clocks all drift ahead -- they're currently 8 minutes fast after
about a month of uptime.  Should I be running ntpd processes in each
of the guest domains that update from the dom0 ntpd?  Or is there some
smarter way to do this?

        Thanks,
