vmpooler_client.py

The “vmpooler_client.py” script provides the ability to manage vmpooler

resources in the vcloud. Currently the script supports grabbing

a new VM for testing and handing a VM back to the pooler to be

destroyed.

To get help on the command-line for the script use the command:

vmpooler_client_app.py -h
