------- Comment #1 from delder@xxxxxxxxxxxxx  2006-07-24 09:14 -------
I'm getting the same problem.  I'm using SLES 10 on a Pentium D dual core
(x86_64) with full virtualization enabled for a SLES 9 guest OS (32 bit). 
Here's a snapshot of my dmesg output:

I was originally able to install 2 xen vms and run them ok so I don't know why
the crash on startup everytime now.  I did notice that one of the vms seems to
crash everytime it is starting up postgresql.  Additionally, if I change from
vnc to sdl for the local viewer I will somtimes lose the whole system, not
tjust the vm (a power cycle is needed).  Any workaround or update would be
greatly appreciated.
