If you would like to use Spice to give you keyboard and mouse input along with clipboard sync support, make sure you have a <code><graphics type='spice'></code> device, then:
* Find your <code><video></code> device, and set <code><model type='none'/></code>
** If you can't find it, make sure you have a <code><graphics></code> device, save and edit again
** On older libvirt versions, just disable the device in Windows Device Manager
