Clustering Virtual Machines
Clustering Software in Virtual Machines
Network Load Balancing, Microsoft Clustering Service and Veritas Clustering Service
run without modification in virtual machines on ESX Server 2.1.
Use of clustering services in virtual machines provides high availability with less
hardware (such as machines and network adapters).
Clustering Scenarios
Several scenarios are possible for clustering in virtual machines.
Cluster in a Box — This provides simple clustering to deal with software crashes or
administrative errors. The cluster consists of multiple virtual machines on a single
physical machine. It supports shared disks without any shared SCSI hardware. It
supports heartbeat network without any extra network adapters.
A four-node cluster on a single physical machine; each node is running clustering software
