Hi,
You can post future questions about LTM configuration in this forum:

A virtual server is defined by an IP address and port. As long as you use a new port, you can define many VS's on the same IP address. If you want to share an IP and port for multiple applications configured in different pools, you can use an HTTP class or iRule to select the pool.
If this isn't the type of information you were looking for, can you clarify what you're trying to accomplish?
Thanks, Aaron
