Havn't looked at it for ages. Should be doable though. Note just some shared memory area isn't enougth, you need also some channel for screen updates (guest->host) and mouse/kbd events (host->guest). One possible approach would be coding up a vnc server, so you can use any vnc client to see the uml framebuffer and talk to the virtual machine. This would also allow remote access to the display. uml-x11-fb never worked with a remote display, probably because it grooks when it can't write to the X11 socket buffer, which quickly happens without the MIT-SHM extention. cheers, Gerd ------------------------------------------------------------------------- SF.Net email is sponsored by: The Future of Linux Business White Paper from Novell.
