Hi,

i have the following problem at an NetBSD 3 / Xen 2.0.7 environment:

I did run a 'make install' for Xorg-Server and KDE in the dom-0 and 4 
dom-U in a test environment at the same time.
After a 2 days and nights it finished and all seems fine. Then shutdown 
the dom-U's stopped xend and shutdown the
dom-0. A day later i'd start NetBSD as dom-0 again. All fine. The try to 
start the dom-U's. All did start with this output:

I'd setup the dom-U's in disklabel partitions. For each dom-U one 
disklabel partition.

Here the disklabel output from dom-0:

So the first dom-U is at i: the second at j: and so on to 4 dom-U's. I'd 
use whole hard disk for the
basic NetBSD installation and did use an Install-CD from this
ftp://iso3.de.netbsd.org/pub/NetBSD/iso/3.0/i386pkg-3.0.iso
image for it.
Till installing Xorg and KDE i could start and stop the dom-U's as often 
as i wish, without any problem.
Any idea what could the reason for my problem and what to do?
I am not sure if it is a god idea to run fsck_ffs in those dom-U's. If i 
really should, i am also not sure with
what parameter.
I fear the hard disk is going to say good by, but i hope i'm wrong.

Oh, one further question, is procfs integrated in the netbsd-XENU kernel 
or do i have to use this entry
in the fstab for linux compatibility?:

 procfs  /proc   procfs   ro,linux    0 0

If any further information is needed, let me know.

thanks in advanced,
Rainer
