Unfortunately, setting the BAR registers doesn't work under KVM.  It 
works fine in QEMU so it's probably a KVM bug.  I'll look into it when I 
get a chance.

[kvm-devel] Problems with vmwarevga and graphical syslinux menus

2008-03-12 Thread Jeremy Katz
The changes so that the vmwarevga code respects the E820 region runs
afoul of the fact that the VBE bios used has a hard-coded base address
for vesa modes.  Thus when syslinux uses VBE to do its graphical bits,
the lfb address doesn't match what the bios thinks it is :-/

Test case is any Fedora boot.iso or live CD from the past year or so.
