Well last year I installed a 32-bit WinXP instance under 64-bit OpenSuSE
host implementation of Xen.
Of course, proprietary technology is not actually paravirtualized, but
rather fully virutalized with the help of the (AMD CPU in my specific case)
hardware extensions. You can find an overview of what I did, if interested
of course, at:

SSH is not in the picture. We are using the pc Hummingbird 
client, another admin says he remembers commenting out 
a line from an X config file , and then being able to
connect using xdmcp . 

Has nothing to do with xhost, I've tried all 
variations.

You probably need to start your ssh session using the "-X" switch. That

will enable xforwarding. 
ssh -X somehost at mit.edu

Or, you may need to add those hosts to your xhost table.
xhost +somehost at mit.edu

I thought ur facing issues with your root file system. 

The file system that ur facing issues won't be mounted in runlevel 1
right?. Can you run the same command for the device that is mounted to
/ora_za3

Thanks,
Krishnaprasad

I can't do that because the root file system is mounted in run level 1 
and it says

WARNING!!! Running e2fsck on a mounted filesystem may cause
SEVERE filesystem damage.

Or, is it ok to run it even though it's mounted.

Did you mean boot from a CD rom?
