Re: Running X server in domU?

[Mark H. <mar...@xs...>]

Hi Sean,


I've been strugling along that path, but have had little time to work on
it recently, so I don't have any progress to report.

I did manage to get one step beyond where you are now, meaning, I got a
version of X patched to work without a VT.
(recent debian based distro's seem to include the patch by default, I've
moved to using Ubuntu Hoary, which uses xorg 6.8.2-10 and has said patch
included).

Next problem I ran into was some IO access problem. I have not had the
chance to investigate that further, but I got a hint from Ian about patching
Xen to allow this IO (not sure how safe that is though).
I was also thinking that, since X does not really have a need for the IO
access, perhaps X could be patched (was planning to try with fbdev driver,
since that should not have any need for other IO).
See this post:
http://article.gmane.org/gmane.comp.emulators.xen.devel/3013/match=hurenkamp

I don't know when I will have more time to investigate, it can be a very
time consuming issue to track, since it probably involves several rebuilds
of Xorg and/or Xen.


Anyways, I wish you good luck, and am very interested if you have something
of interest to report :-).
When I have some more info, I'll also report back here.


Mark.
