I added my point to the bugzilla and everyone on oVirt should do so in
my opinion... very frustrating.. ;-(
And it seems not so easy to change gluster range.
I read in past threads for previous versions that the range 24009+ was
written inside the code.
In 3.4 it should be an option such as
--volfile-server-port=PORT
from a client point of view... but I tried some things and not able to
arrive at a significant point... always 49152 and 49153 used for my
two bricks

Furthermore, as a side note, I wanted to try migration reattempt it
several times as each time it chooses next port.
I have two bricks so that the first two attempts fail; in VM.log I get
...
-incoming tcp:[::]:49152: Failed to bind socket: Address already in use
...
-incoming tcp:[::]:49153: Failed to bind socket: Address already in use

Unfortunately, tested three times with same result, after the second
attempt the dest node goes into a loop of failing, recoverying from
crash, non reposnive.
I easily correct the situation with

systemctl restart vdsmd

on it, but possibly I could have raised some sort of bug.
And then if I try again to migrate it restarts from 49152... so I
cannot test it.

See here below a file with what written in vdsmd.log, with the two
attempts and the failure and the loop of type

Thread-61::DEBUG::2013-10-10
01:15:32,161::BindingXMLRPC::986::vds::(wrapper) return
getCapabilities with {'status': {'message': 'Recovering from crash or
Initializing', 'code': 99}}
