[Xen-users] domUs kernel panic on boot

[michael@xxxxxxxxxx]

I've been having a problem with newly created domUs kernel panicking when
I start them, below is a copy of the errors I'm getting.  I'm running
CentOS 4.4 with the Xen 3.0.3 RPMS from xensource.com.

Usually when this happens the guest will restart itself and boot normally.
 Any ideas what would cause this?
