I have noticed something with all my HVM domU's, and that is that the
time jumps forward, in two hours after having synchronized the clock
it will be like half hour forward. I have tried everything I have
found on the subject, like setting localtime=1 and setting timer_mode
= 1,2 or 3 with no success, it still jumps forward really fast. I also
found a bug report[1] about this problem from 2007 that is still open
with no comments from developers, which leaves me thinking if it is
really a bug or more of a missconfiguration of HVM domU's as this
doesn't happens with my PVM domU's.

I'm missing any configuration to get the clock working fine on HVM
domU's ? of course I could convert them to PVM but they are around 20
of them so if there's some configuration I could do to them to fix
this issue it would be a lot better.

I'm running CentOS 5.5 x86_64 (for both dom0 and all domU's) with
default Xen 3.0.3.
