Hi Kasturi,

thank you for your reply. Here are my versions:

gdeploy-2.0.2-7.noarch
ansible-2.3.0.0-3.el7.noarch

The file /usr/share/ansible/gdeploy/scripts/grafton-sanity-check.sh is 
missing. For the sake of completeness, the entire directory ansible is 
missing under /usr/share.

In /var/log/messages there is no error message, and I have no 
/etc/ansbile/ansible.cfg config file...

I'm starting to think there are some missing pieces in my installation. 
I installed the following packages:

yum install ovirt-engine
yum install ovirt-hosted-engine-setup
yum install ovirt-engine-setup-plugin-live ovirt-live-artwork-gnome 
libgovirt ovirt-live-artwork ovirt-log-collector gdeploy 
cockpit-ovirt-dashboard

and relative dependencies.

Any idea?

Simone
