You can use a separate network for bricks when you create a gluster volume.

To do this:

1. Create a logical network (non-VM)
2. Assign "gluster" network role and add it to the cluster.
3. From Host -> Networks sub tab, click on Set up networks, and assign 
the network with "gluster" network role to the interface that you want 
to use for the bricks. Make sure that an IP address is assigned to the 
interface, and the gluster network role is correctly assigned on the UI.

Now, when creating a volume, the bricks will use the interface's IP in 
Step 3.

(Ovirt cannot work with multiple hostnames for a host currently, so 
there's no support to create the brick with alternate FQDN, only 
alternate IP addresses will work for the bricks)
