host
VM-Marketing
In the following example, assume that VM-QA is memory intensive and accordingly you want to change the
resource allocation settings for the two virtual machines to:
n
Specify that, when system memory is overcommitted, VM-QA can use twice as much memory and CPU
as the Marketing virtual machine. Set the memory shares and CPU shares for VM-QA to High and for
VM-Marketing set them to Normal.
n
Ensure that the Marketing virtual machine has a certain amount of guaranteed CPU resources. You can
do so using a reservation setting.
Procedure
1
Start the vSphere Client and connect to a vCenter Server.
2
Right-click VM-QA, the virtual machine for which you want to change shares, and select Edit Settings.
3
Select the Resources and In the CPU panel, select High from the Shares drop-down menu.
4
In the Memory panel, select High from the Shares drop-down menu.
5
Click OK.
6
Right-click the marketing virtual machine (VM-Marketing) and select Edit Settings.
7
In the CPU panel, change the value in the Reservation field to the desired number.
8
Click OK.
If you select the cluster’s Resource Allocation tab and click CPU, you should see that shares for VM-QA are
twice that of the other virtual machine. Also, because the virtual machines have not been powered on, the
Reservation Used fields have not changed.
Viewing Resource Allocation Information
Using the vSphere Client, you can select a cluster, resource pool, standalone host, or a virtual machine in the
inventory panel and view how its resources are being allocated by clicking the Resource Allocation tab.
This information can then be used to help inform your resource management decisions.
Cluster Resource Allocation Tab
The Resource Allocation tab is available when you select a cluster from the inventory panel.
The Resource Allocation tab displays information about the CPU and memory resources in the cluster.
