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

["Emre Erenoglu" <erenoglu@xxxxxxxxx>]

For VNC:
Method 1:
- make VNC available on your domU configuration file
- load framebuffer in DomU and start Xorg-server on that
- you don't need network inside DomU, as VNC port is listening on Dom0 side (and displaying the DomU framebuffer)

Method 2:
- install xserver-xorg with vnc framebuffer inside domU
- you don't need framebuffer driver of xen inside the domU, but yes for VNC framebuffer
- you need network inside DomU and this shall be reachable from the external the network
- you don't need to enable VNC in your dom0

for NX:
- you need networking for your DomU, domU shall be reachable over the network.
- you need kde/kdm inside your DomU
- you don't need anything else

Please ask other questions to clarify if you need,

Br,

Emre

I have to say, that I am confused :-). I have got one of the feelings
that I am completely stupid.

Just to summarize the steps:

After I installed clean DomU

Do I have to install xserver-xorg on domU   |yes/no| yes
DO I have to configure ? xserver-xorg       |yes/no| yes
                                       (vesa framebufer)
Do I have to install KDE, kdm               |yes/no| yes
Do I have to install vnc4server             |yes/no| no
Do I have to add some ? line in domU config |yes/no| no

Then I can run vncviewer from any workstation on the network do domU and
it should work?

Thanks Jiri
