dockur

With dockur you can run Windows inside a Docker container. It's a really funny project,because it runs kvm insidea docker container. I did not try it yet, but maybe in the near future i will. Also nice for inspiration to build other virtual-machines in docker.

virt-backup

• virt-backup - hot external backups of your Libvirt guests, using the BlockCommit feature. The goal of virt-backup is to do an automatic backup system, with optional compression, and be able to easily restore a backup.
