Spontaneous reboots when running WinXP DomU

[Mayuresh <mayuresh%acm.org@localhost>]

Following command outputs should describe the setup in detail.

I find the host booting spontaneously on following scenarios:

1. When winxp installation is going on, on DomU at a certain stage of
installation the host reboots.

2. If I try to "xl shutdown -F winxp" it doesn't work. Doing "xl destroy
winxp" leads to hanging the host followed by a reboot after some time.

Please have a look at the below specs and advise.
