[virt-tools-list] [iGVT-g] GVT-g - suboptimal user experience

virt-manager and virt-viewer essentially run the same code spice client
code: both are using the spice-gtk widget.  So, if that isn't working
(didn't verify) it should be rather easy to wire up.

That works fine, you can just set the video card model to "none" in
libvirt xml.  Not sure whenever virt-manager allows to do that via GUI,
maybe you have to use "virsh edit" instead.

Works.  Needs cutting edge software versions though (qemu 4.0 and linux
kernel 5.1 on the host).

That one is for intel to answer ...
