Re: [libvirt] [PATCH v3 2/4] conf: add optional attribte primary to video <model> element

If there are multiple video devices primary = 'yes' marks this video device as the primary one. The rest are secondary video devices. No more than one could be mark as primary. If none of them has primary attribute, the first one will be the primary by default like what it was. The reason of this changing is that for qemu, only one primary video device is permitted which can be of any type. For secondary video devices, only qxl is allowd. Primary attribute removes the restriction that the first have to be the primary one. We always put the primary video device into the first position of video device structure array after parsing.
