Thank you, Andrea. After following your instructions I re-enabled it back to check to see if it will log any messages from shutdown but no. I've noticed however that the computer no longer freezes at shutdown. I am not sure why but it looks like the problem is gone now. I will try to debugg it deeper and if I have any issues I will get back to you. Jędrek 10 lip 2017 08:36 "Andrea Bolognani" <abologna@redhat.com> napisał(a):

I'm not familiar with the libvirt codebase, but the extension of libvirt-guests.sh indicates that it is a shell script. Maybe you can modify it to find the spot where it hangs?
That's indeed the case. On Debian/Ubuntu system, the script is installed as
/usr/lib/libvirt/libvirt-guests.sh
and you can definitely try debugging it if you're familiar with shell scripting.
I installed both libvirt-bin and qemu-kvm in an Ubuntu 16.04 guest in an attempt to reproduce the issue you're having but I was unsuccessful, so I'm afraid I can't really help you much further.
It would probably be a good idea to open a downstream bug report with your vendor, as they might have an easier time reproducing the issue.
It's worth noting that the libvirt version included in Ubuntu 16.04 is a bit old (it was released a year and a half ago), however the libvirt-guests script hasn't changed very much in the meantime.
