I've two Mint VMs in Virtualbox. One hosts internal services and has critical data. The other is hosting services exposed to the internet and has no data of value.

I think I can paravirtualize one of these VMs, I think using docker. I'd end up with a single image I could then easily migrate to physical hardware.

Am I on the right track? I've no problem figuring out how. But, I'm not sure which means is best and why.
