What we do here is get vgabios into a file, and then tell our emulator to use the file as the 'C segment' but to use /dev/mem for everything else. In that way we init the physical hardware. X11 ought to do this but I do not know if they support the option it at this point. It's easy: our code is just mods to the X11 emulator. Is there any easy way to dump the mfn's for a guest -- that would tell us right away what is going on -- we should see pfn 0xc0 map to mfn 0xc0, i.e. dom 0 physical c0000 maps to vga bios at machine 0xc0000. This is where having /proc/sys/xen/dom/#/{mem,mfn,etc} would be VERY handy :-) ron ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
