Re: [libvirt-users] [iGVT-g] GVT-g - suboptimal user experience
So it looks like this solution is currently not very user friendly. Perhaps Intel could
get Red Hat help to make first-class support of gvt feature in virt-manager?

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.
Currently it doesn't work. Only following methods do work:

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.
It doesn't allow it via GUI.

Works. Needs cutting edge software versions though (qemu 4.0 and linux
kernel 5.1 on the host).
Ok, I will test it with later versions someday. However I assume dynamic resolution (on
window resize) is not supported?

That one is for intel to answer ...
