VM Pool management via API

I'm currently working on a project to be able to create VM pools, and manage them completely from a perl written API.

The problem I'm facing, is once I've created a pool of x amount of VM's, I don't see any way to control them or get any information about them when using the API. It doesn't appear that the vm's created in a pool have vm id's.

Basically what I need to be able to do is create a pool with 50 VM's for example, start these VM's (and stop), and get the mac addresses of each one. Is this possible?
