I tried Gluster deployment after cleaning within the Cockpit web console, using the suggested ansible-playbook and fresh image with oVirt Node v4.4 ISO. Ping from each host to the other two works for both mgmt and storage networks. I am using DHCP for management network, hosts file for direct connect storage network.

I've tested the command on a test Gluster 8.3 cluster and it passes.Have you checked the gluster logs in '/var/log/gluster' ? I know that there is LVM filtering on oVirt 4.4 enabled, so can you take a look in the lvm conf : grep -Ev "^$|#" /etc/lvm/lvm.conf | grep filter

VDO is using lvm.conf too, so it could cause strange issues. What happens when the deployment fails and you rerun (ansible should be idempotent) ?
