Hi,
Checking the logs I see only 2 host out of the three you mentioned.

TASK [Gathering Facts] *
ok: [ovnode1.pop3.metamakers.org]
ok: [ovnode3.pop3.metamakers.org]

Can you also paste the hc-wizard inventory file as well.You can find
it here*/etc/ansible/hc_wizard_inventory.yml*

Well almost. Create a new cluster and  (Check) Enable Gluster Service .
Upon adding new hosts to this cluster (via ui) gluster will be
automatically configured on them.

Hi,
You can try this.
Engine-UI -> Compute -> Clusters -> New -> (Check) Enable Gluster Service
-> (Check) Import existing gluster configuration -> Enter details of one
gluster host.
Engine will add all host in peer with gluster under the new Cluster.

 Steps if you use ovirt-engine and ovirt-node on two seperate physical
servers
 1. Server1 install ovirt-engine
 2. Server2 install ovirt-node
 3. Set bridge network using the link on ovirt-node (
https://www.ovirt.org/develop/developer-guide/vdsm/installing-vdsm-from-rpm.html#configuring-the-bridge-interface
 )
4. Add ovirt-node to ovirt-engine

Yes this is possible
1. install ovirt-node on one physical machine
2.Install ovirt-engine-appliance on ovirt-node (yum install
ovirt-engine-appliance)
3. Steps to install self-hosted engine using cockpit (

Hope it solves your issues.

Can you send the logs for host-deploy.

/var/log/ovirt-engine/host-
deploy/ovirt-host-deploy-20181208085622-139.59.88.157-422c2a61.log

You can try this.
1. Mark all your existing hosts in Maintenance
2.Go to Clusters -> select your cluster -> edit -> Mark 'Enable Gluster
Service'
3. Go to Host Window -> Click on Installation ->  Reinstall
This should install gluster pacakges and enable gluster service in you
cluster
