      I haven't looked into this very much, but it sounds promising.
    Anyone on list familiar with it?

It is, in essence, LXC containers combined with an overlay filesystem. 
It's basic PaaS with a Go binary ("docker") wrapped around LXC. It's 
neat in the same sense as Vagrant -- you can ship a Dockerfile which can 
reproduce your environment very easily, and the Docker team itself has 
wrapped all the images in a git repository you can easily branch 
from/etc. That said, Docker support won't land in Fedora until F20, and 
CentOS around the same time (officially).

I'll admit that I don't get the hype around Docker, since it doesn't do 
anything that LXC doesn't already do, but the templating and a 
user-friendly binary is nice.

    I wonder if there's interest in shipping oVirt docker containers.

I'm interested in Docker to ease the process of building Node images, at 
least. oVirt Docker containers would be interesting, assuming LXC 
support isn't painful, since the CoreOS (where Docker originated) also 
relies on an image with readonly root and overlays on top, so there's 
some overlap.
