Not able to ping from VM1 to VM2

Hi Team,

I have Installed VMWare Workstation 9.0.2, named it as OracleVM1-H (HostName). Later I cloned it, named it as OracleVM2-H (Host Name).

Using IP Address I can ping from each other. (OracleVM1-H to OracleVM2H and  OracleVM2-H to OracleVM1H)

Using Host Name I'm not able to ping any of it.

Please find the attachment for ifconfig, /etc/hosts O/P.

Thanks in advance.
