[Xen-users] Unhandled page fault in domain <x> on VCPU 0 (ec=000

Hi,

I finally managed my raid controller to work (not corrupt data) underXen - see my previous thread.But now, when I start an earlier created domain (which worked finepreviously), strange things happen.


p-dom0:/etc/xen# xm create p-file.cfg -c
Using config file "./p-file.cfg".
Started domain p-file

(no console shows up)

p-dom0:/etc/xen# xm dmesg

p-dom0:/etc/xen# xm list

Name ID Mem VCPUs StateTime(s)Domain-0 0 2894 4 r-----604.7p-file 322 384 1--p--- 0.0

I can't shutdown the domain in the 'nice' manner: it keeps showing up,as if it's in some loop. So far xm destroy seems to work.

I recompiled the xenU kernel, without any success.

Any idea what can be causing this?
