I have numerous problems with my para- and hardware- virtualizated guests.
Clock in guests drifts up to many days. Sometimes it happens after xendomains 
service saves and restores state on reboot, sometimes not, sometimes it 
happens when I am sleeping :). I use latest fedora 8 with latest updates (I 
have had problem since fedora 6 ...)  My proc settings:
/proc/sys/xen/permitted_clock_jitter is 10000000
/proc/sys/xen/independent_wallclock is 0
In hvm guest i tried localtime=0 and rtc_timeoffset=0 but nothing helps.
In paravirt. there is nothing to set ...
I want to use xen widely in my job but this problem is quite annoying and
can make serious damage so ...
I do not want to use ntp as solution now.
Could you help me please ? Google does poorly ...
