Xen users - Apr 2009 - How to set up GUI guest on non-GUI server?

Hello:

I have a CentOS 5.3 server I installed without a GUI.
It uses the xen kernel.

I am trying to install a guest that will have a GUI.

I was thinking I could set up VNC for the display
of domain0, but all of the attempts I have made so 
far have failed.

Can someone point me in the right direction?

Thanks,
	Neil

Install vncserver od dom0 and change:

(vnc-listen ''127.0.0.1'')

to either ip address od dom0 or 0.0.0.0 and if you use for domU
guests: vnc=1, vncviewer=0 and you will be able to connect from other
machine by typing:

vncviewer ip_address_dom0:ID_of_domU

This is very easy to accomplish if you use HVM guest, but also it is
possible if you use paravirtualized guests.

Here is one of the many useful links:

Vlado:

That guide assumes there is already a text-based domU
guest.

I am trying to do a new guest install using the GUI
during the install.  Is that possible?

I am not making the difference if you are working on the guest that
already exists or you are making a new one. I just want to point that
you have to spawn vncserver on domU, listening on ID port(or manual
port) that dom0 has it. And if you have concern installing vncserver
on the dom0 itself, that is another story. Thats another vncserver
running on domU itself.

In short words I think that you have to enable sdl and vnc graphics on
your guest start if you want to use any graphics on that guest at all.
Those are two basic approaches for managing guests in xen. You also
may use X forwarding, Freenx, rdesktop(only for Windows guests), PCI
Device Assignment(for more read in Prentice Hall - Running Xen, A
Hands On Guide to the Art of Virtualization).
