Using Parallels Virtual Automation to manage Virtuozzo Containers? Look no further, now with HostBill you can provision both Windows and Linux Containers!
In Apps->Add new App section provide your virtuozzo node details. Replicate this step for each node you wish to provision accounts on using HostBill.
Use test connection to make sure HostBill is able to connect with node. If its not possible, try enabling SSL mode and make sure that Parallels Agent is up and running on your node.
