[one-users] Zones in 4.6

Hi Alberto,

If you see your 5 IT VMs in the UK opennebula, maybe is because the whole
master DB was copied into the slave, and not just the few tables needed for
the OpenNebula federation.

Can you please confirm that the dump made during this step [1] only
contains these tables:


Those same tables should be the only ones in the slave's my.cnf [2].
