Hi, I''m not certain whether this belongs in ''users'' or ''devel'', the topic appears to turn up in both lists. I''ve started here on the assumption that it already works and I''ve missed something :) What we''d like to do is run several independant X11''s on a single CPU box. Using on-board (AGP) graphics, and additional (PCI) graphics cards, and various USB controllers for the keyboard/mice combos. The aim is to have three ''consoles'', each with a browser running to provide access to our library catalogue. With Xen we should be able to isolate each console in its own dom, ensuring that one user can''t so easily ruin others functionality. I''m running Debian 3.1 sarge/stable as dom0. I''ve got Xen 3.0.2 stable sources and built them with to include the pciback module. Using pciback I can happily have various devices show up in domU (ethernet, USB controller and graphics) with things like ''lspci''. The obvious stuff just plain works - I can use the ethernet card instead of the virtual ethernet, find USB devices. I ''upgraded'' domU to debian unstable, to get a more recent Xorg setup, but I still get stuck. Using "X -novtswitch -sharevts vt1" I ended up being told: -------------- copy of end of X output starts -------------- (EE) I810(0): Cannot map SYS BIOS Fatal server error: xf86MapVidMem: Could not mmap framebuffer (0x000a0000,0x10000) (Bad address) -------------- copy of end of X output ends -------------- At this point I''m out of ideas :) Anyone have any pointers or ideas?
