Re: [Xen-users] NTP service in DomU

Hi Jordi,

well, you're right. It's not possible to have
independent ntp clients running in your domU's because
you only have one physical harware clock, right? ;)

And I can't really understand your argumentation about having
serveral domU's "around  the world"? In that case, don't you have
also several dom0's arrounf the world at that places?
