Hi I appreciate that this is a very basic question .... I have installed Xen and managed to create a few Domains running Debian and Gentoo. In both cases I then attempted to create a Desktop environment by installing X but hit some problems. Searching through the archives it seems that an X environment is not yet supported within a Domain, and hence I guess the setting up of Gnome/KDE ? If this is the case are people currently using the Domains purely as command line interfaces? Looking at the various images there seemed to be a Desktop environment supported in some way.

Stewart, the Xen live CD runs the guest OSs with GUI. To me that means: It is definiteley possible. I haven''t been able to start the GUI on my DomUs up til now. As far as I could figure out, the live CD DomUs run a VNC server to which the Dom0 connects to. I spent some hours connecting the DomU to a Dom0-X-server (according to my opinion this should also be feasible) but it failed on some X-authorization-stuff... The DomU received a rejection from the Dom0-X-server. In other words, the communication seemed to work but the authorizations were not set properly. This might not be exactly what you wanted to know... all I can say is that X/Gnome/KDE is possible - and I also would be pleased if somebody could name a HOWTO or anything else which could help here. Thanks! Cz.

The demo CD runs "vncserver" automatically in a domain, which creates a virtual X display you can connect to using VNC.> I spent some hours connecting the DomU to a Dom0-X-server (according to my > opinion this should also be feasible) but it failed on some > X-authorization-stuff...

Just SSH to a domain using "ssh -X domain", then run an X application. It should appear in a window, just like it would if you were SSH-ing to a real machine.> This might not be exactly what you wanted to know... all I can say is that > X/Gnome/KDE is possible - and I also would be pleased if somebody could > name a HOWTO or anything else which could help here.VNC, Xnest and FreeNX are also good things to look at. SSH with X forwarding is probably the simplest.

Thus they can be used *by one* (am I right?) domU. So what if I don''t show dom0 the video-card? Depending on the dom0-OS, it may even work that dom0 can still show up stuff (totally unsure, I am have not yet begun reading VGA-specs or alike ;-) ) however, just a sitenote. I actually started to setup my Xen-puter with two VGA-cards, so that''d be another possibility basing on the above assumption(s). But now that is all a bit hackish, it would be interesting to see a real hardware-API here; virtual-soundcards, virtual video-devices, and so on and so forth. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I can say I''ve ever tried booting Linux without a video card, though.> Depending on the dom0-OS, it may even work that dom0 can still show up > stuff (totally unsure, I am have not yet begun reading VGA-specs or alike > ;-) ) however, just a sitenote.Probably depends on the version of Xen too - I think Xen 3.0 is a bit stricter about IO privileges.> I actually started to setup my Xen-puter with two VGA-cards, so that''d be > another possibility basing on the above assumption(s).A few people have been trying to get a second graphics card (and USB keyboard, mouse) running in a second domain. They haven''t managed it (AFAIK - please let us know if you have) yet but hopefully they''ll get it working some time. It''s certainly something we''d like to see.> But now that is all a bit hackish, it would be interesting to see a real > hardware-API here; virtual-soundcards, virtual video-devices, and so on > and so forth.With Intel''s LaGrande security tech (AMD have a similar thing but I can''t remember the name) we''ll be able to regulate things much better so that we don''t have to trust domains with direct hardware access. We''ll be able t control where they may DMA to, etc. This also implies most fault-resistant driver domains will be possible.
