Previously, I used MPICH2 to launch my application. But recently I had to use 
openmpi and when I started on 2 nodes, it gives an error:

Open MPI detected an inbound MPI TCP connection request from a peer that 
appears to be part of this MPI job (i.e., it identified itself as part of 
this Open MPI job), but it is from an IP address that is unexpected. This is 
highly unusual.

The inbound connection has been dropped, and the peer should simply try again 
with a different IP interface (i.e., the job should hopefully be able to 
continue).

Local host: node2

Local PID: 6029

Peer hostname: node2([[40861,1],2])

Source IP of socket:192.168.122.1

Known IPs of peer:

I run mpiexec -np 4 -machinefile ./hostfile ./test_hello  mpi=2x2.

Contents of the file hostfile:
192.168.56.1 slots=2
192.168.56.2 slots=2

Whats the problem?
