6.4. CPU Quality of Service
CPU quality of service defines the maximum amount of processing capability a virtual machine can access on the host on which it runs, expressed as a percent of the total processing capability available to that host. Assigning CPU quality of service to a virtual machine allows you to prevent the workload on one virtual machine in a cluster from affecting the processing resources available to other virtual machines in that cluster.

-
Click
. - Click a data center’s name to open the details view.
- Click the QoS tab.
- Under CPU, click New.
- Enter a QoS Name and a Description for the quality of service entry.
-
Enter the maximum processing capability the quality of service entry permits in the Limit (%) field. Do not include the
%symbol. - Click OK.
You have created a CPU quality of service entry, and can create CPU profiles based on that entry in clusters that belong to the data center.

Removing a CPU Quality of Service Entry
-
Click
. - Click a data center’s name to open the details view.
- Click the QoS tab.
- Under CPU, select a CPU quality of service entry and click Remove.
- Click OK.
If any CPU profiles were based on that entry, the CPU quality of service entry for those profiles is automatically set to [unlimited].
