Ganeti – virtual machine cluster management tool

Ganeti is an open source cluster virtual server management software tool built on top of existing virtualization technologies such as Xen or KVM and other Open Source.

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

Ganeti is written in Python and Haskell.

Features include:

  • Support for Xen virtualization:
    • Support for PVM and HVM instances.
    • Live migration support.
    • Virtual console (on PVM) or VNC (on HVM) to control instances.
    • Support for virtio or emulated devices.
  • Support for KVM virtualization: (from Ganeti 2.0):
    • Live migration support.
    • Support for fully virtualized instances.
    • Support for semi-virtualized instances (kernel residing on the host).
    • Support for VNC or serial access.
    • Support for virtio or emulated devices.
  • Recommended cluster size 1-40 physical nodes.
  • Disk management:
    • Plain LVM volumes.
    • Files (from Ganeti 2.0).
    • across-the-network raid1 (using DRBD) for quick recovery in case of physical system failure.
  • Instance disk partitioning supported from Ganeti 2.0.
  • Export/import mechanism for backup purposes or migration between clusters, or
  • Automated instance migration across clusters.
