[Xen-devel] No video display, SuSE kernel-xen-2.6.11.4-21.7

[Robbie Dinn <robbie@xxxxxxxxxxxx>]

Thread moved from the xen-user to xen-devel mailing list

Ian, I have done some limited testing, I will do some more,
but I wanted to report what I had so far.

I am doing this testing on my Mitac laptop but I may
switch to different hardware for future tests. There
is no serial port on the laptop and you can't change
the video card.

I am using the same linux kernel through out but changing the
Xen version each time. This wasn't what you asked me to do
but I thought it was worth doing before I got bogged down
with recompiling kernels.

I will try different kernels next.
