[libvirt-users] domain xml <video> doubt

Hi My libvirt is 3.4.0,When I create a kvm domain, I use default <video> (type=cirrus, I not set video) create guest(debian9.1.0), but when finish install the guest and reboot, the guest will block in "started update utmp about system runlevel changes", I search on Internet, and find is graphics card problem, I change the <video> type=vga, the problem disppear。The domain xml docs say， I can set type=qxl, ...， but qemu -vga args has other type support, (qemu --help, -vga [std|cirrus|qxl....), I want to know how I use other <video> type in my domain xml. Thanks very!!!
