Hello, lads, owing to i study video card on my guest recently.
So i have a notion that whether we can get video with virtio-vga or not.
It's seem that we are using a graphics card truth.
Maybe we can finish? 
And if this is not likelihood? Tell me why please.
following is my host system environment:
host: ubuntu 1604
qemu: 2.11
libvirt: 3.9
kernel: 4.14
guest: window 7 professor
