Use Cluster Server (VCS) in both the guest and host to enable an integrated solution for resource management across virtual machines and physical hosts. You can create a physical to virtual cluster combining VCS in a KVM guest together with VCS running on another physical host, enabling VCS to:
Monitor applications running within the guest
Failover applications to another physical host
Failover an application running on a physical host to a VM virtualized guest machine
