IRejuvenation is applied on all VMM and VM subsystems in both hosts.
IIRejuvenation is not applied only on one of VMM subsystems in two hosts, but also on both VM subsystems in two hosts.
IIIRejuvenation is applied on both VMM subsystems in two hosts but not applied on only one of two VM subsystems.
IVRejuvenation is not applied on haft side of the system including VMM1 and VM1 subsystems but applied on VMM2
and VM2 subsystems.
