RE: [Xen-users] NTP time issues DomU's

[Tim Durack <tdurack@xxxxxxxxx>]

I think it's perfect the way it is.

Run NTP in dom0, all the domU's then have synchronized time.

I can still set timezones on all of these boxes independantly.
Timezone has nothing to do with NTP synchronization.

If you don't run ntp in the domU's, it should just work.

If you want to run ntp in the domU, try:
 echo 1 > /proc/sys/xen/independent_wallclock

I guess we could be smarter about this, and make the wall clock
independent automatically if someone does an adjtimex syscall. Anyone
got any comments on this?
