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.)
