Re: [Xen-users] How to make KDE or Gnome available in DomU?

["Emre Erenoglu" <erenoglu@xxxxxxxxx>]

If you are able to use Paravirtual DomU kernel with a Xen Framebuffer, you don't need to setup any vnc inside the domU.

The framebuffer driver in DomU will serve as the source of screen information to the xen daemon running in dom0, this will give you vnc access without installing any vnc in the DomU itself.

Hi Emre.

I have to do something wrong somewhere. Here is what I did.

I use paravirtual DomU. The aim is to access is remotely through VNC
(for start).

I installed xserver-xorg and I installed KDE plus kdm.

I ran dpkg-reconfigure xserver-xorg and xorg sugested vesa driver (I
have Nvidia card in my HP DL145 G2 server), and I choose to use
framebuffer. Then I went through the other options like monitor etc.
(default settings).

I restarted and :

 2302 ?        Ss     0:00 /usr/bin/kdm -config /var/run/kdm/kdmrc
 2331 pts/0    R+     0:00 ps ax

I then installed vnc4server. As normal user I executed vncpasswd (set
password) and vnc4server to start the session.

But the vnc session does not come up. What I do wrong?
