Ganeti

Ganeti is a virtual machine cluster management tool built on top of existing virtualization technologies such as Xen or KVM and other open source software. Ganeti requires pre-installed virtualization software on your servers in order to function. Once installed, the tool assumes management of the virtual instances (Xen DomU). Ganeti controls

Disk creation management,
Operating system installation for instances (in co-operation with OS-specific install scripts), and
Startup, shutdown, and failover between physical systems.

Ganeti is designed to facilitate cluster management of virtual servers and to provide fast and simple recovery after physical failures using commodity hardware.
