Ah, now I see.  Testing it on xen-unstable does, indeed, show xm block-detach
working as expected.  There were some changes made in the meantime that actually
make it work.  That means the first hunk of my changes to DevController.py
aren't required.  However, I think the other two hunks are actually "correct",
even though we don't see the xm block-detach bug in current xen-unstable.  That
is, they move the device section from /vm/UUID/device/tap to
/vm/UUID/device/vbd, which seems more right to me.
