parentMove TSS pages to allow a larger BIOS image (diff)
Move EPT identity mapping pages to allow a larger BIOS image
Move from: 0xfffbc000-0xfffbcfff to: 0xfeffc000-0xfeffcfff This step is required to free up the 0xff000000-0xffffffff (16MB) range for use with bios.bin. The KVM kernel change depends upon a change to kvm/bios/rombios.c so the bios INT15-E820 function will properly reserve the new location. Signed-off-by: Jordan Justen <> Signed-off-by: Avi Kivity <>
