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

Create a CPU quality of service entry.

Creating a CPU Quality of Service Entry

  1. Click ComputeData Centers.
  2. Click a data center’s name to open the details view.
  3. Click the QoS tab.
  4. Under CPU, click New.
  5. Enter a QoS Name and a Description for the quality of service entry.
  6. Enter the maximum processing capability the quality of service entry permits in the Limit (%) field. Do not include the % symbol.
  7. 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.

3.4.2. Removing a CPU Quality of Service Entry

Remove an existing CPU quality of service entry.

Removing a CPU Quality of Service Entry

  1. Click ComputeData Centers.
  2. Click a data center’s name to open the details view.
  3. Click the QoS tab.
  4. Under CPU, select a CPU quality of service entry and click Remove.
  5. 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].
