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

["Emre Erenoglu" <erenoglu@xxxxxxxxx>]

Hi Mark,

you don't need a framebuffer to use NX. You don't need any video hardware at all. You just need KDM or GDM, with necessary gnome/kde environment packages. error about kstartupconfig may mean some configuration error with kde, no home directory etc.

Hi

I'm trying to do something similar: run a NX server within a Xen guest. I have
Ubuntu Gutsy as host and Ubuntu Edgy as guest, and amd64 architecture.  Am
using paravirtualisation and the framebuffer within the guest.

I get as far as a KDM error page but no futher:
"Could not start kstartupconfig. Check your installation."

Clicking on an OK shuts down the NX screen. Do you have any suggestions?

Thanks

M
