Hello,

Ron Sigal has done some investigation, and come up with this explaination. JBoss remoting is the thing making the connection, by setting up a org.jboss.remoting.stream.StreamServer, which creates a ServerSocket. This ServerSocket is bound to the address returned by InetAddress.getLocalHost() by default. On my machine that was the ethernet interface, eth0, which I disconnected prior to attempting to make a connection to the TEIID server. If there is no network connectivity on this interface, when an attempt to make a connection is made, we get the error in question. 

We can force StreamServer to create a ServerSocket on a different interface, eg, localhost, by setting the system property "remoting.stream.host", to "localhost". To do that, add the following line to the end of $EDS_HOME/bin/run.conf.

JAVA_OPTS="$JAVA_OPTS -Dremoting.stream.host=localhost"

Please test your VM environment using this setting, and let us know the result.
Regards,
Jason

> When trying to create a preview a datasource using the Teiid designer, an error dialogue is shown, and the EDS server.log shows an error containing this message. This only happens when there is no network connectivity on the machine, for example the network cable is unplugged.
> [IOException]Can not find a free port for use
