Hi, 
I just have two virtual machines in my environment, I want them to gracefully stop when host is powered off gracefully. 

Nevertheless, system hangs on shutdown:

[root@vdicnode01 ~]# virsh list
 Id    Name                           State
----------------------------------------------------
 1     vdicdb01                       running
 2     vdicone01                      running

The configuration:

/usr/libexec/libvirt-guests.sh
URIS=default
_ON_BOOT_=ignore
_ON_SHUTDOWN_=shutdown
SHUTDOWN_TIMEOUT=60
PARALLEL_SHUTDOWN=5
START_DELAY=0
BYPASS_CACHE=0
CONNECT_RETRIES=10
RETRIES_SLEEP=1
SYNC_TIME=0

[root@vdicnode01 ~]# cat /etc/libvirt/qemu.conf
user  = "oneadmin"
group = "oneadmin"
dynamic_ownership = 0
spice_tls = 0

With libvirt-guests service started:
[root@vdicnode01 ~]# service libvirt-guests status
Redirecting to /bin/systemctl status  libvirt-guests.service

[root@vdicnode01 ~]#

If I stop locally libvirt-guests (as root) Looks work perfectly:

[root@vdicnode01 ~]# virsh list
 Id    Name                           State
----------------------------------------------------

[root@vdicnode01 ~]#

--> Now I start again the virtual machines and the libvirt-guests service <--
[root@vdicnode01 ~]# service libvirtd restart
Redirecting to /bin/systemctl restart  libvirtd.service
[root@vdicnode01 ~]# service libvirt-guests start
Redirecting to /bin/systemctl start  libvirt-guests.service
[root@vdicnode01 ~]# virsh list
 Id    Name                           State
----------------------------------------------------
 1     vdicone01                      running
 2     vdicdb01                       running

[root@vdicnode01 ~]#

But If I shutdown the host it look not work properly (I attack screenshots of the shutdown process).

Any help will be welcome.

Thanks a lot.
