a distributed VM management tool

What is minimega?

minimega is a tool for launching and managing virtual machines. It can run on your laptop or distributed across a cluster. minimega is fast, easy to deploy, and can scale to run on massive clusters with virtually no setup.

OpenStack and other VM-management tools need lots of configuration and they're still slow! minimega requires no configuration beyond a few optional command line arguments--it can even deploy itself to other cluster nodes if needed. It launches VMs fast, too; in a few seconds, you can launch and start as many VMs as your physical memory can hold--but thanks to minimega's KSM integration, duplicated memory pages will be compressed and you can start even more VMs!

The minimega repository also includes several more tools and libraries to make VM creation and cluster management easier
