cloud - Is it possible to have Docker On VM? -

i thinking whether can have docker on top of guest os. layered blueprint thinking of

i have containers run on top of docker , hence feel can address multi-os feature alongside docker

please suggest if such implementation possible or not?

that looks boot2docker implements already, with:

• host os windows or mac
• virtualbox
• tiny core host docker (meaning, no persistence except /var/lib/docker, noted in answer: use virtualbox extension pack mount guest host home directory)
• docker
