Packstack fails on chkconfig --add libvirtd

Hi all,
I am using packstack to deploy openstack on top of Centos 7.2. This week everything was fine in a sense packstack completed successfully and openstack was up and running. Today, I ran the exact same command and same answer file but i got the following error during packstack execution:

Applying 10.240.121.12_nova.pp
10.240.121.10_nova.pp: [ DONE ]
10.240.121.11_nova.pp: [ ERROR ]
Applying Puppet manifests [ ERROR ]

the nova.pp.log says:

My environment is: 1 controller from which packstack is executed and 2 compute nodes.
My versions:
[root@c00b00 packstack]# rpm -q puppet
puppet-3.8.7-2.el7.noarch

[root@c00b00 packstack]# rpm -qa|grep packstack
openstack-packstack-puppet-8.0.0-1.el7.noarch
openstack-packstack-8.0.0-1.el7.noarch

My other system i installed this week has a different version of puppet (3.6.2-4), I tried to force install this one while packstack was running but it didn't help...

My CentOS 7.2 does uses systemctl framework and running the command chkconfig --add libvirtd fails in both systems.

Does anyone know what is happening?
