Subject: Xen on Ubuntu: DomU hangs on boot



Hello,

I am trying to install Xen, and I followed the directions at:
http://www.howtoforge.com/ubuntu-7.10-server-install-xen-from-ubuntu-repositories

The physical machine and Dom0 boot fine.

However, I can't seem to get any DomU to start.


To clarify:

After I issue the "xm create xen_domu_name"
command, no errors are returned, and the "xm list" command shows
something like this:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Name                                      ID   Mem VCPUs      State   Time(s)
Domain-0                                   0   239     1     r-----   
 279.0
xendomu                                    7   128     1     -b----     27.5
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

However,
I am unable to ssh into the VM, and typing anything at the "xm console"
screen yields no response.  (Though, the "xm console" does show the
scroll back listed below.)

Any help would be appreciated.

Thank you,
Allen
