Hi all!
I am running SXCE 121 on a dual quad-core X2200M2 (64 bit of course).
During an installation of a NetBSD 5.0.1 PVM domU, the entire machine
crashed with a kernel panic. Here's what I managed to salvage from
the LOM console of the machine:

Here is the XML file I have used to "virsh define" the domain:

(HTML entities inserted for the poor forum readers :-)
Note that even though I had the NetBSD install ISO specified as a disk,
I ended up running the actual installation via NFS because the names
on the image would not map correctly (some RockRidge problem I guess).
In /var/log/xen/xend.log I see only INFO and DEBUG messages dating
from before the panic. The crash occurred during unpacking of the
distribution sets (.tar.gz) via NFS3 from localhost:/tmp.
Has anyone seen this crash before? What could I do to keep the box
from crashing while I continue my experiments?
Thanks -- Volker
