[libvirt] [PATCH v2 0/4] use newer video device by -device in qemu commandline

[Guannan Ren]

v2: check qemu version, it has to be qemu >= 1.2 for using
       new video device with -device qemu option

This patch set aims to use qemu VGA device with -device option to replace
-vga option. The mapping is as follows.

'-device VGA' maps to '-vga std'
'-device cirrus-vga' maps to '-vga cirrus'
'-device qxl-vga' maps to '-vga qxl'
     (there is also '-device qxl' for secondary devices)
'-device vmware-svga' maps to '-vga vmware'

Through this change, guests will be able to use any available PCI slot
number rather than fixed 0x2 slot for primary video device.
