So, are people doing something like running one container per vm? I have yet to do more that run Docker's whalesay container, but I figured the obvious thing to do is to either use an entire blade with one OS on it, or provision a single, large, vm and run many containers. If anyone feels like sharing, how do you deal with persistent data? Like mysql databases, uploaded files, logs, etc. I'll eventually be googling it, but figured it couldn't hurt to get pointed somewhere by people who have experience. :)
