I followed the steps listed in the following link to install a Ubuntu guest VM on xen: http://fosshelp.blogspot.com/2013/03/how-to-create-pv-guest-vm-on-ubuntu.html .
However, on starting the VM installation through 'xm create' the installation mostly goes through successfully but after that the VM goes down with a halt signal as seen below:

On researching more on this side, I found that I need to make use of pygrub to start the halted guest domain. But I haven't had much success in this regard.
Can the experts over here please let me know if I am missing something very basic over here.
Accepted AnswerRussell PavlicekOnline0Hello Sharad,
Xen 3.1.2 is very, very old -- from 2007 I believe. Not only has a lot happened to the software since then, but even community support is long finished for that release. And people with experience with that release are growing fewer in number.
Now, if you are not able to upgrade, I suggest the following:
1. You are relying on information from a blog probably written for 4.3 or 4.2. It may contain information which is not the best for the 3.1 release. It would be better to use a reference more suited for such an old release. Maybe you'd be better off using a manual like the Xen 3.3 manual:
2. If the new manual does not give you better results, look for log files created during the "xm create" action. Inspecting the logs could explain the failure.
3. If none of that works, I suggest gathering up your config file and any log files you might find, and send the question to the xen-users mailing list. There may be people on that list who know enough about that release to be helpful.
