creating a new VM defaults to Spice graphics interface but the required client s/w is not installed failing VM init

[Andy Whitcroft]

When creating a VM the default video "connection" type is Spice this triggers the machine to create to fail with the error below:

((null):3909): Spice-ERROR **: reds.c:3213:do_spice_init: statistics shm_open failed, Permission denied

Switching to VNC fixes this.

We should be defaulting to something installed.
