virtualcontrol is a configuration and monitoring tool for QEMU/KVM instances on a linux box. virtualcontrol primarily uses the KVM command line tools to do its job. Apart from trivial functions like starting and stopping virtual machines, virtualcontrol also allows freezing/thawing virtual machines (snapshot including memory dump), KVM machine migration and advanced storage functions like HA and dedicated storage solutions (OpenSANd).

Features

  • Controls KVM virtual machines
  • Written entirely in Perl, uses command line tools shipped with KVM
  • Allows easy configuration of large IP networks connecting virtual machines
  • Automatic restart of virtual machines, based on time of day or shutdown event
  • Uses NBD in order to connect to OpenSANd, an open storage area network solution
  • Integrated NBD proxy solution provides I/O statistics for each disk and allows to transparently survive temporary SAN disconnects
  • HA available through VM migration and transparent SAN disk mirroring
