CentOS - Jan 2019 - libvirt guest on host's shutdown/reboot - problem

hi guys

I have just two guest after which libvirt looks and when I shutdown 
those guests:

$ virsh shutdown $_dom

that domain takes little time to power down, as expected one would 
say(~20sec) But! I reboot the hosts and I have in my:

/etc/sysconfig/libvirt-guests :

ON_SHUTDOWN=shutdown

PARALLEL_SHUTDOWN=1

SHUTDOWN_TIMEOUT=300

I see libvirtd service shut down takes minutes, a few good minutes to 
deal with guests shutdown(I suppose?)

How could I dig into it and troubleshoot?

Would you have any idea as why libvirtd shutdown takes that long?

many thank, L.

How long does it take if you do this?

systemctl stop libvirt-guests.service

I have PARALLEL_SHUTDOWN=5 with currently four guests and it takes as you
said ~20-30 seconds (those are non systemd guests).
