OK, I tried and succeed to create a new cluster.
In this new cluster, I was ABLE to add the first new host, using
its mgmt DNS name.
This first host still has to have its NICs configured, and (using
Chrome or FF) the access to the network settings window is
stalling the browser (I tried to restart even the engine, to no
avail). Thus, I can not setup this first node NICs.
Thus, I can not add any further host because oVirt relies on a
first host to validate the further ones.
Network team should be able to help you here.
OK, there were no mean I could continue this way (browser crash), so I
tried and succeed doing so :
- remove the newly created host and cluster
- create a new DATACENTER
- create a new cluster in this DC
- add the first new host : OK
- add the 2 other new hosts : OK
Now, I can smoothly configure their NICs.
Doing all this, I saw that oVirt detected there already was existing
gluster cluster and volume, and integrated it in oVirt.
Then, I was able to create a new storage domain in this new DC and
cluster, using one of the *gluster* FQDN's host. It went nicely.
BUT, when viewing the volume tab and brick details, the displayed brick
names are the host DNS name, and NOT the host GLUSTER DNS names.
I'm worrying about this, confirmed by what I read in the logs :

"cluster52" is the recent cluster, and I do have a dedicated gluster
network, marked as gluster network, in the correct DC and cluster.
The only point is that :
- Each host has its name ("serv-vm-al04") and a second name for gluster
("serv-vm-al04-data").
- Using blahblahblah-data is correct on a gluster point of view
- Maybe oVirt is disturb not to be able to ping the gluster FQDN (not
routed) and then throwing this error?
