Description Kamil Páral 2016-12-06 11:05:51 UTC 
Description of problem:
Freshly created VMs in virt-manager now have <vmport state='off'/> tag under <features> (this tag is not present in VMs created in the past). For such VMs, latest mutter-3.22.2-1.fc25.x86_64 broke X11 sessions - only black screen is displayed.

The solution is either to downgrade to mutter-3.22.1-8.fc25.x86_64, or remove the <vmport state='off'/> tag from the VM configuration. The "vmport" tag seems to be "emulation of VMware IO port", per this documentation:
https://libvirt.org/formatdomain.html
https://www.redhat.com/archives/libvir-list/2015-April/msg00000.html

When things are broken (VM with vmport tag and latest mutter), this appears in journal:

Version-Release number of selected component (if applicable):
mutter-3.22.2-1.fc25.x86_64 (not working)
mutter-3.22.1-8.fc25.x86_64 (working)
gnome-shell-3.22.2-2.fc25.x86_64
kernel-4.8.11-300.fc25.x86_64

How reproducible:
always

Steps to Reproduce:
1. create a fresh new VM in virt-manager on Fedora 25 host
2. make sure the VM has <vmport state='off'/> by inspecting "virsh edit VMNAME"
3. install latest Fedora 25 in the VM
4. upgrade mutter to 3.22.2-1.fc25
5. see that you can't log in to X11 session any more
6. downgrade mutter and see you can log in to X11 -- or -- remove <vmport state='off'/> from "virsh edit VMNAME" and see you can log in to X11
