Xen project Mailing List

[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
