> We use HTTP to interact with the images from the command line (we have several hundreds images running on each server, so its a bit more convenient than using VNC ;). It is a combination of bash, curl and Seaside. On the image side we have a simple request handler that calls methods with arguments passed via query strings. From the command line we can do stuff like "cbfor beta-testers disableLogin", which sends the message #disableLogin to all images in the beta-tester group.

> To manage the VM processes we use daemontools (http://cr.yp.to/daemontools.html), and again various scripts to automate installation, configuration, version upgrading, etc.
>
> For monitoring we use Nagios, and Munin. Former also uses the HTTP interface to check images for their health.
