[Q] Second, does the primary patch allow Xen''s VNC to connect to the
GPU instead of emulated graphics? If not, does anyone know whether it would be
possible to
connect Xen''s VNC to the emulated graphics?
[R] Perhaps you should clarify your question. AFAIK I will say yes but you may
have only the qemu console (black screen). This is the expected behavior. The
only solution should be to install VNC on the domU.
On Windows 7 setting gfx_passthru=0, (in Xen''s VNC ) let me to have
access to the domU while booting..until the Windows logo appears. Then screen
switches to my real desktop.
But I don''t think it is what you are asking for...The best solution is
to install a default vncserver on the domU!
[Q] First, is there a host for the patch or is it only what was released to the
mailing list in the past?
[R] Yes it si only what was released to the mailing list in the past. I just did
a test a couple minutes ago for the latest changeset 26906.
Due to changeset 26827
(xenbits.xensource.com/hg/staging/xen-unstable.hg/rev/23a6084b223a?revcount=240)
tools and studbom are installed in /usr/local.
Letting prefix set to /usr/local didn''t work for me. I did so many
tests on my machine and to keep a workable workstation I just changed
.... ./configure --prefix=/usr
And it worked
Below are the command lines I used
hg clone -r 26906 http://xenbits.xensource.com/staging/xen-unstable.hg/
xen-unstable.hg-rev-XXXX
cd xen-unstable.hg-rev-XXXX
CURL=$(which curl-config) XML=$(which xml2-config) ./configure --prefix=/usr

Objet : [Xen-users] AMD Primary Passthrough Question
Hello,
I am about to try the AMD patch to test primary passthrough and had a couple of
questions.
First, is there a host for the patch or is it only what was released to the
mailing list in the past?
Second, does the primary patch allow Xen''s VNC to connect to the GPU
instead of emulated graphics? If not, does anyone know whether it would be
possible to connect Xen''s VNC to the emulated graphics?
Thanks in advance,
~Casey
