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:

Cool. Is the video maintainer OK with the Xen maintainers stashing it
in the Xen tree for Linus?
Thanks!
