hello
i think we need to back out of vagrant first.
if you have a template with a fixed IP on it, you can use only one.
Vagrant won't help there.
So, you can implement a DHCP, save a new template that uses DHCP, and then vagrant can spin more than one.
Vagrant talks to VCSA and query information about the VM (so you need to have vmtools there) and will grab the IP that got assigned.
from there vagrant will be able to connect to this new VM using the user vagrant and the known public/private ssh key.
Alvaro.
