After discussing with other maintainers, we don't think hot plugging
emulated devices can be supported by upstream. [0]

In this particular case, the fix is going to make nic hotplug support pv
by default. If you try to plug in an emulated device, you still get the
same error.

That being said, you can poke QEMU via QMP socket to do things as you
see fit. Xen toolstack creates a QEMU monitor socket in /var/run/xen,
you can use the QMP script in QEMU source code to connect to that socket
to do things.
