VMmanager Cloud makes it possible to deploy a fault-tolerant cluster and build high-availability cloud infrastructure. If one of the nodes is down, VMmanager distributes its VMs between the remaining nodes one by one.

The system consists of operational nodes for running virtual machines and fail-over network storages such as iSCSI, Ceph and GlusterFS for locating VM discs. VMmanager Cloud uses Corosync to detect availability of every VM within a cluster.
