Xen users - Feb 2007 - Re: pci graphics in paravirtual domU

xen-gl is under active development at this point. Of course beta testing 
will help greatly :)
I am a bit forgetful wrt to syncing my page with reality. Expect a few 
updates soon.
Nevertheless, the code is usable afaik. It''s working fairly decently
for
me and some other people that have emailed me.

Thanks for the update!

As not seldomly Xen stuff breaks between minor releases, it might be a
good idea to publish information about with which xen versions you
have testet it on the website.

I''ve seen a lot of howtos and docs which I tried, just to find out
they only work with two minor versions of Xen ago, so I am a bit
hesitant to test everything without seeing there''s a chance to get it
working on up to date versions.

The code is GPU-independent, VMM-independent, and guest-OS independent. 
I only provide Linux compiles for now, I''ve played some serious quake 3
on freebsd and OpenSolaris guests.
It should work regardless of your Xen version. It works on VMware too, 
tested and sworn affidavit :)
I recommend Xen 3.0.4 . Xen 3.0.3 has a tiny glitch on the netback code 
that freezes high-throughput connections. I use 3.0.3 with a one-liner 
patch for that glitch.
I do not endore my own rpm''s (for now). Please build the tarball.
