Re: [Xen-users] Time freeze in domU after reboot

[Sadique Puthen <sputhenp@xxxxxxxxxx>]

Hitting https://bugzilla.redhat.com/show_bug.cgi?id=426861 ?

Can be worked around by configuring the guest to sync to ntp after 
setting up  xen.independent_wallclock = 1 to /etc/sysctl.conf and 
running "sysctl -w" in the guest.
