This can't be done on EC2. The network doesn't work that way. –  womble May 13 '12 at 11:27

To make sure the new alias (virtual interface) is working, you can try to ping the new assigned IP locally from each node. If you got a reply, it ensures you defined the new alias correctly.

If you could not connect from one instance to another using the new alias, you may not be allowed to the assigned IPs or you have a routing/network issue.
