Ganeti started as a small project at Google. Google has been using
ganeti internally , and now google is going to share it under GPLv2.
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.
Features
Ganeti provides the following features for managed instances:
* support for Xen virtualization
* recommended cluster size 1-25 physical nodes
* disk management using either plain LVM volumes, local-disk raid1
mirrors or across-the-network raid1 (using DRBD) for quick recovery in
case of physical system failure
* export/import mechanism for backup purposes or migration between clusters
Ganeti does not offer
* live migration support
* fully virtualized instances (only paravirtualization support)
