Edit a Resource Pool
After you create the resource pool, you can edit its CPU and memory resource settings.
Prerequisites
Launch the vSphere Client and log in to a vCenter Server system.
Procedure
1 In the vSphere Client, right-click the resource pool in the inventory and select Edit Settings.
2 In the Edit Settings dialog box, you can change all attributes of the selected resource pool as described
in “Create a Resource Pool,” on page 353.
3 Click OK to save your changes.
Add a Virtual Machine to a Resource Pool
When you create a virtual machine, the New Virtual Machine wizard allows you to specify a resource pool
location as part of the creation process. You can also add an existing virtual machine to a resource pool.
When you move a virtual machine to a new resource pool:
n
The virtual machine’s reservation and limit do not change.
n
If the virtual machine’s shares are high, medium, or low, %Shares adjusts to reflect the total number of
shares in use in the new resource pool.
n
If the virtual machine has custom shares assigned, the share value is maintained.
NOTE Because share allocations are relative to a resource pool, you might have to manually change a
virtual machine’s shares when you move it into a resource pool so that the virtual machine’s shares are
consistent with the relative values in the new resource pool. A warning appears if a virtual machine
would receive a very large (or very small) percentage of total shares.
n
The information displayed in the Resource Allocation tab about the resource pool’s reserved and
unreserved CPU and memory resources changes to reflect the reservations associated with the virtual
machine (if any).
NOTE If a virtual machine has been powered off or suspended, it can be moved but overall available
resources (such as reserved and unreserved CPU and memory) for the resource pool are not affected.
Prerequisites
Launch the vSphere Client and log in to a vCenter Server system.
Procedure
1 In the vSphere Client, select the virtual machine in the inventory.
The virtual machine can be associated with a standalone host, a cluster, or a different resource pool.
2 Drag the virtual machine (or machines) to the resource pool.
If a virtual machine is powered on, and the destination resource pool does not have enough CPU or memory
to guarantee the virtual machine’s reservation, the move fails because admission control does not allow it.
An error dialog box displays available and requested resources, so you can consider whether an adjustment
might resolve the issue.
