Xen on Ubuntu: DomU hangs on boot

[Allen Fowler]

The command as listed does seem to work.. it gives an error:

"mount: can't find /my/test/dir in /etc/fstab or /etc/mtab"

That being said, i did try regenerating the DomU disk image anyway.   Things still don't work,  but obviously it's much further along.

Here is what's happening after I create the DomU now:

- "xm top" show it running at 99% CPU.  (even after 1hour+ of waiting)
- "xm console" show a backlog, but no interactive prompt. (this is w/ "extra = 'xencons=tty'")
- I can't ssh into the DomU

Thanks

Here is the new "xm console" log:
