There is no reasons why an HVM guest shouldn't be allowed to use xenfb. As a matter of fact ARM guests, HVM from Linux POV, can use xenfb. Given that no Xen toolstacks configure a xenfb backend for x86 HVM guests, they are not affected. Please note that at this time QEMU needs few outstanding fixes to provide xenfb on ARM: http://marc.info/?l=qemu-devel&m8739419700837&w=2
Cool. Is the video maintainer OK with the Xen maintainers stashing it in the Xen tree for Linus? Thanks!
