Correct it is fully booted. This is the same thing shown on a normal
linux boot. I have attached both logs for reference. The linux one
is not exactly the same kernel, but it is close (both are rc7)
The vanilla linux one doesn't have any xen dom0 patches.

On the normal linux one, even when putting the console on
the serial port, gdm loads up on the monitor, but this
doesn't happen for the dom0 kernel.

However I can SSH into the dom0 kernel fine.

/proc/xen/capabilities is missing, so xend does not start.

Any ideas on how to get xend working. Just let me know
what logs you need etc.

Glad that I can help.

I will check this. I also want to change my Xen testing temporarily to the
Dell 755 (VT-d), which also has a VGA monitor (not DVI) so that may
make testing easier (assuming that the dom0 kernel can work on
my 755 box).

I'll report back more progress as I can

Cheers,
Todd
