Re: [Xen-devel] Dom0 <> DomU clock sync

[Keir Fraser <Keir.Fraser@xxxxxxxxxxxx>]

You're not running ntpd in the domU as well, right? Just worth checking...
Apart from that I don't think you can be doing anything wrong. Any weirdness
after long uptime is of course interesting, as it's something that's hard
for developers to test.

If you create a new domU (doesn't need to be from scratch installation -
e.g., just restarting a domU, or starting an existing dormant domU, would
do) then is its time behind dom0, or in sync?
