I would like to submit a request for a "virtulization appliance".
We wanted to build and deploy a server to a remote office. We decided to use VirtualBox to deploy the application. We also decided to use the Core ISO as the host OS for virtual box. This process was somewhat painful because of all the dependencies needed to install and run VirtualBox (hours instead of minutes).
The virtulization appliance would have all the dependencies resolved and automatically ready to receive it's first guest OS.
Let me know if we can help with this process since we have already done this step once.
