Yes, but since the machine is a standard Ubuntu Linux Server machine,
I'm not sure how an OVA will help you. You still have to assign your IP
addresses, turn on routing, etc. per the instructions in the Wiki.
In the time it would take you to transfer it the file, you could simply
have the same thing by running the ISO on a fresh VM.
Are you having issues with setup?
