3.4. 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.
3.4.1. Creating a CPU Quality of Service Entry

- Enter the maximum processing capability the quality of service entry permits in the Limit field, in percentage. Do not include the
%symbol. - Click .
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.
3.4.2. Removing a CPU Quality of Service Entry
Remove an existing CPU quality of service entry.
Procedure 3.8. Removing a CPU Quality of Service Entry
- Click the Data Centers resource tab and select a data center.
- Click QoS in the details pane.
- Click CPU.
- Select the CPU quality of service entry to remove.
- Click .
- Click when prompted.
