While not exactly the same thing, I got Critic running in Docker on my Mac. Docker is a light weight Linux runtime, and on Mac also includes a VM with very little overhead.

I manage it through a little shell script that will install, start and update/upgrade Critic. This script should work just the same on Linux, but I haven't tried it there.

On Mac, install Docker + Boot2Docker. They are available as homebrew recipes:

brew install docker
brew install boot2docker

boot2docker init
boot2docker up
boot2docker shellinit

Then use critic-docker:

cd critic
critic-docker install
critic-docker run

hack, commit

critic-docker update

One caveat is that you currently can't specify a custom postgres host/port as an installation parameter, and I didn't bother to fix that, so you need to add "host": "postgres" to data["installation.database.parameters"] in installation/database.py. (In the critic-docker setup, postgres is run in a separate Docker container exposed with the hostname postgres to the main Critic container.)
