7 Select what to do with the host’s virtual machines and resource pools.
n
Put this host’s virtual machines in the cluster’s root resource pool
vCenter Server removes all existing resource pools of the host and the virtual machines in the
host’s hierarchy are all attached to the root. Because share allocations are relative to a resource
pool, you might have to manually change a virtual machine’s shares after selecting this option,
which destroys the resource pool hierarchy.
n
Create a resource pool for this host’s virtual machines and resource pools
vCenter Server creates a top-level resource pool that becomes a direct child of the cluster and
adds all children of the host to that new resource pool. You can supply a name for that new top-
level resource pool. The default is Grafted from <host_name>.
8 Review settings and click Finish.
The host is added to the cluster.
Adding Virtual Machines to a Cluster
You can add a virtual machine to a cluster in a number of ways.
n
When you add a host to a cluster, all virtual machines on that host are added to the cluster.
n
When a virtual machine is created, the New Virtual Machine wizard prompts you for the location to
place the virtual machine. You can select a standalone host or a cluster and you can select any
resource pool inside the host or cluster.
n
You can migrate a virtual machine from a standalone host to a cluster or from a cluster to another
cluster using the Migrate Virtual Machine wizard. To start this wizard, right-click the virtual machine
name and select Migrate.
Move a Virtual Machine to a Cluster
You can move a virtual machine to a cluster.
Procedure
1 Find the virtual machine in the vSphere Client.
a To find a virtual machine, select a data center, folder, cluster, resource pool, or host.
b Click the VMs tab.
2 Right-click on the virtual machine and select Move To....
3 Select a cluster.
4 Click OK.
Removing Virtual Machines from a Cluster
You can remove virtual machines from a cluster.
