Hello,
I'm trying to test what found here:
http://blog.wikichoon.com/2016/05/spice-openglvirgl-acceleration-on.html
and here:
https://www.kraxel.org/blog/tag/virgl/
My system is a fedora 25 laptop, born in version 23 and gradually updated
to 24 and 25 now.
I had a fedora 25 guest that worked ok with "normal"spice and I'm trying to
configure with virgl
Main components currently installed on host:
qemu-kvm-2.7.0-7.fc25.x86_64
libvirt-2.2.0-2.fc25.x86_64
virt-manager-1.4.0-4.fc25.noarch
VirtualGL-2.4-7.fc25.x86_64
Commands executed to modify configuration:

I don't know if the WARNING above is a generic one or if it makes any
pre-check to system...
Anyway both from vrt-manager and virsh I get error
[root@ope46 qemu]# virsh start f25
error: Failed to start domain f25
error: internal error: process exited while connecting to monitor:

What can I check? Any pre-requisite in laptop video adapter or other?
Thanks in advance,
