Re: [libvirt] [PATCH] Fix explicit usage of default video PCI slots

Don't set the PCI address of primary video to the default

Without this, a primary video card that doesn't have an
address gets the default one on the 1st pass of PCI address
allocation, even if it's occupied. This address gets picked
up by the second pass, and a conflict occurs:
XML error: Attempted double use of PCI slot 0000:00:02.0
(may need "multifunction='on'" for device on function 0)
Also fix the test that was supposed to catch this.
And does it actually work after this patch? IIRC, the primary video card
is forced to be at 0000:00:02.0 by QEMU. That is, if this address is
occupied by another device, there should be no way to add a video card.
