It's always 0, except with virtio.

But I think virtio linux driver multi-monitor code would work with a single
qemu head (like qxl, fwiw last time I checked, multi-monitor virtio+spice
worked, with 3d too). It seems to me the qemu "head" is quite different
(lower-level) from spice "head".

The relation would need to be clarified imho before we expose this option.
