Cluster doesn't work with more than 1 node.. (no replies)

I'm trying to start a new cluster with 2 single nodes.. ndb_mgmd server starts normally, ndbd connections from 2 nodes starts normally too, but when I try to start mysqld engine I can't..
Looking into ndb_1_cluster.log, I see the error:

2014-06-16 11:40:59 [MgmtSrvr] WARNING -- Failed to allocate nodeid for API at 10.0.0.3. Returned error: 'No free node id found for mysqld(API).'
2014-06-16 11:40:59 [MgmtSrvr] WARNING -- Failed to allocate nodeid for API at 10.0.0.2. Returned error: 'No free node id found for mysqld(API).'
