Handled already, look on HLD for
'qxl' - spice device, 'cirrus' - vnc device
iirc, there is supposed to be something around being able to use both
vnc or spice (mutually exclusive) without rebooting the guest.
i.e., user would be able to connect with either one of these protocols
Dor/Alon?
another item (shouldn't affect design i hope, but just in case):
I just heard spice multi monitor support for linux guests may work
differently than for windows.
in windows we expose 4 video cards.
for linux we may need to create one card with 4 times the memory.

I think those will be handled as (un-managed) vm-device abd by definition can have
multiple entries
but having/not having spice configured would affect the need for one of
them (spice-vd-agent)
and cluster compatibility would affect the need for the qemu-ga one (not
sure if that would be configurable or assumed as default for all guests)
