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.
