Yes, I read that one, and it got me some headache, but not in these 
server. Thanks anyway for the answer.

The upgrade was done fine for all the server of the cluster (the 
external one was installed directly with 7), their machine-id are all 
different and network communication between hosts has no problems.

The problem I got is just between this specific host and the VM it is 
hosting (also between VM on the same network in other hosts and the ones 
inside this server, but that just because these are unreachable from the 
host itself).
