I guess it really depends on whether its possible to get video.S to work (allow the same mode selection as Linux) with a simple hack or weather it is much more involved. >When dom0 takes over the VGA console (which is the default mode >of operation) you can arrange to put it into whatever mode you >like; you just won't get the initial boot messages from Xen in >the extended text mode. > > I was looking at modifying the hypervisor because I couldn't get this to work and couldn't find a specific reference stating it was possible. I have the following lines in grub and it doesn't set the video mode title Xen 2.0 / XenLinux 2.6.9 root (hd0,0) kernel /boot/xen.gz dom0_mem=131072 console=vga module /boot/vmlinuz-2.6.9-xen0 root=/dev/sda6 vga=0x133 I have tried various permutations of this with no success.
