Hi,

I've created a 3 host based hosted engine. I can't add other hosts to hosted engine's cluster.

Before the setup, I have created a 3 node glusterfs for hosted engine on them.

Because I would like use and separate vlans, I created two vlan bridge on all host. First is for ovirtmgmt, and a second for glusterfs.

The hosted engine setup was successful but when I try to add other hosts, that is does not work, because vdsmd could not started. 

I found some network related errors in the logs:

restore-net::ERROR::2017-09-19 19:14:48,072::__init__::51::root::(__exit__) Failed rollback transaction last known good network.

The four host network config is same, the ovirtmgmt bond.104 is the default route.

How can I add another host to cluster?
