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.

Ganeti is very suitable for Linux-users that want expand from a single
virtualisation host to a small cluster. In this presentation I will show
you how easy it is to start your own cluster.
