Ian Jackson 7d278e2115 xl: Document VGA problems arising from lack of physmap dmop ...

Ross reports that stdvga guests do not work, and cirrus guests are
slow, because qemu tries to do xc_domain_add_to_physmap.  We will need
another dmop to fix this properly.

For now, document the problem.

(In the cirrus case, the vram remains mapped at the old guest-physical
addresses, while the guest runs.  We are not sure whether this is a
correctness or security problem and we should advise against it.)
