Description:

Ganeti is a cluster virtual server
management software 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 will take over the
management part of the virtual instances (Xen DomU),
e.g. disk creation management, operating system installation
for these instances (in co-operation with OS-specific install scripts),
and startup, shutdown, failover between physical systems.
It has been designed to facilitate cluster management of virtual servers
and to provide fast and simple recovery after physical
failures using commodity hardware.
