Re: [libvirt] [RFC PATCH v2 00/18] Introduce vGPU mdev framework to libvirt

since v1: - new <hostdev> attribute model introduced which tells libvirt which device API should be considered when auto-assigning guest address - device_api is properly checked, thus taking the 'model' attribute only as a hint to assign "some" address - new address type 'mdev' is introduced rather than using plain <uuid> element, since the address element is more conveniently extendable. - the emulated mtty driver now works as well out of the box, so no HW needed to review this series --> let's try it :) - fixed all the nits from v1
