I also alternatively tried putting the following into xen-unstable.hg/.config:
QEMU_UPSTREAM_URL = git://git.qemu.org/qemu.git
QEMU_UPSTREAM_REVISION = master

Then executed make world, which doesn't have the above problems of
checkout, but during the build has the following error in the
qemu-xen-dir-remote:

ERROR
ERROR: User requested feature xen
ERROR: configure was not able to find it
ERROR

Thanks,
David
