libvirt video device models
The libvirt virt driver supports setting the device model for the video device used to back the guest display via the image metadata
since this feature was introduced new models ( gop, none) have been added to libvirt.

This specless blueprint simply tracks adding the missing values and the required version checks.
video model definitions
gop: The uefi graphic output protocol device model
virtio: A virtual gpu implementing the gallium gpu spec leveraging the virgl renderer to
enable opengl rendering. note this gpu model can leverage hardware acceleration
if the host has a gpu. see https:/
none: The ``none`` video model can be used to disable emulated video devices. this is
useful when using pGPU or vGPU pass through or can also be used when a
graphic terminal is not desired for the guest.
note: while virtio was previously available and enabled by default for AArch64 systems
this blueprint allows it to be used on other architectures.

which will intoduce the ablity to schdule based on device model support
via placement. The spec for that feature is avilable here https:/
and updating the glance metadefs.
note i miss read the code comment virtio is already supported

mearly made it default on AArch64 it did not restrit it to aarch64.

Per the 2019-04-18 nova meeting [1] this is probably OK as a specless blueprint, but efried was going to follow up with kashyap to make sure kashyap was on board with this, but I suspect it will get approved for Train. -- mriedem 20190424
efried 20190425 - kashyap reviewed, sean updated, everyone's happy, approving.
