How to get IP address of Virtual machine

I need to run my program on a unix machine which is hosted in virtual machines.
When my program tries to get IP address of unix machine I am getting an Exception, this I guess is due to program running on Virtual Mahine. Hence my program is not proceeding, can you please let me know how to configure this.

I am able to get my IP address running on Windows machine.

Here is code I am using to run it on Windows

Code:

---

String strAddr = InetAddress.getLocalHost().getHostAddress();
