virtualbox.org

I have my VMs setup and installed on a portable hard drive. I want to be able to carry them with me and use them on a pc at another location.
The VMs are a mixture of Windows and Linux clients.

How is the best way to manage/achieve this. Both hosts are Ubuntu 9.10 machines.

TIA.

Apologies - please disregard...another thread has been posted and I've sussed a way to do it.
