Use Cluster Server (VCS) to provide application monitoring and failover to another KVM guest.
Connects multiple, independent systems into a management framework for increased availability
Enables nodes to cooperate at the software level to form a cluster
Links commodity hardware with intelligent software to provide application failover and control
Enables other nodes to take predefined actions when a monitored application fails, for instance to take over and bring up applications elsewhere in the cluster
