So the problem is in dom0, not actually in Xen.

So that means xend is not running.
Do you have xen-evtchn driver module loaded? Do you have xenfs mounted to
/proc/xen?
Do you have files in /proc/xen/ directory?
See this wiki page for more information about troubleshooting pv_ops dom0
kernel:
http://wiki.xensource.com/xenwiki/XenParavirtOps
Also I recommend you to upgrade to later version of pv_ops dom0 kernel,
2.6.31.5 is pretty old already and many many bugs have been fixed after that.
