[Xen-users] Win 2k3 VM restarting continuously.

[Rajkumar Bhargodeo <Rajkumar.Bhargodeo@xxxxxxxxxxxxxxxxxx>]

Hello,

We have a dom0 system running Xen v4.1.

There are two virtual machines running on this platform one is a windows 2003 
server and other is a RHEL server.

We have installed PV drivers(0.9.11.13) on Windows server.
Issue is that Windows server keeps restarting every 30 Min with the event 
"unexpected shutdown occurred". 
A dump is created C:\windows\memory.dmp when system restarts. When I open the 
dump in WinDbg and execute command !analyze -v output as below is produced. I 
have the dump if someone wants to have a look at it I can send it to him/her. 
When we attempted to install 0.11.0.373 version of drivers system was not 
coming up and entire setup had to be re-installed.

I would appreciate any help or guidance in resolving this issue.
