6.5.1

Cluster Virtual Machines on One
Physical Host 2
You can create an MSCS cluster with up to ve nodes on a single ESXi host.
N Windows Server 2008 SP2 and above systems support up to ve nodes (virtual machines). For
supported guest operating systems see Table 6-2. Windows Server 2003 SP1 and SP2 systems support two
nodes.
A cluster of virtual machines on one physical machine requires a host with one physical network adapter for
the VMkernel. Use a separate physical network adapter for clustered virtual machines to connect with
external hosts.

Create the First Node for Clusters on One Physical Host
To create the rst node, you create and congure a virtual machine with two virtual network adapters and
install a guest operating system on the virtual machine.
You congure the virtual network adapters to handle virtual machine trac for the cluster: a private
network connection for the private heartbeat and a public network connection.
Procedure
1 Open the vSphere Web Client and connect to the vCenter Server system.
Use the user name and password of the user who will have administrator permissions on the virtual
machine.
2 In the vSphere Web Client navigator, right-click the host and select New Virtual Machine.
3 Proceed through the wizard to create the virtual machine.
