Hey FWIW, I have virsh running on my laptop too and no virtual machines registered to autostart but my laptop reboots just fine and shows no traces of any warnings.

Hi Dominik,   So what is going on on my computer with the script libvirt-guests.sh? Why is it hanging on it? How should I address this problem?

Dominik, As far as I am concerned the command provided by Andrea disables libvirt-guests service at boot. jedrek@Home:~$ service libvirt-guests status ● libvirt-guests.service - Suspend Active Libvirt Guests Loaded: loaded (/lib/systemd/system/libvirt-guests.service; *disabled*; vendor preset: enabled) Active: inactive (dead) Docs: man:libvirtd(8) http://libvirt.org When you enable/disable a service *sysctemctl *creates a symlink of a service into the location on disk where systemd looks for autostart files (usually /etc/systemd/system/some_target.target.wants jedrek@Home:~$ ls /etc/systemd/system/ | grep libvirt* libvirtd.service No libvirt-guests.service I know this is just a workaround but what's wrong with this? 2017-07-07 19:13 GMT+02:00 Dominik Psenner <dpsenner(a)gmail.com&gt;: > Note that this disables the shutdown of libvirt guests when the host > shuts down. > > 2017-07-07 16:20 GMT+02:00 Jędrek Domański <jedrek.domanski(a)gmail.com&gt;: > >> Andrea, >> >> You are a genius!!! :D It's worked :)) Thank yo so much!!!

Yeah, I know. Sorry for my demanding attitude.

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. -- Andrea Bolognani / Red Hat / Virtualization

Andrea,   I have libvirt version 1.3.1. I am looking at libvirt.org/sources and see more recent versions. Do I have the most up-to-date version? Do I need to upgrade?   $libvirtd -V  libvirtd (libvirt) 1.3.1

Well, I see newer versions of libvirt on Launchpad so I could just add PPA repository and install newer version from there. Would that work?
