Virtual machines can have resources of a node, such as CPU, dedicated to them in order to improve performance.

About dedicated resources

When you enable dedicated resources for your virtual machine, your virtual machine’s workload is scheduled on CPUs that will not be used by other processes. By using dedicated resources, you can improve the performance of the virtual machine and the accuracy of latency predictions.

Prerequisites
  • The CPU Manager must be configured on the node. Verify that the node has the cpumanager = true label before scheduling virtual machine workloads.

Enabling dedicated resources for a virtual machine

You can enable dedicated resources for a virtual machine in the Virtual Machine Overview page of the web console.

Procedure
  1. Click WorkloadsVirtual Machines from the side menu.

  2. Select a virtual machine to open the Virtual Machine Overview page.

  3. Click the Details tab.

  4. Click the pencil icon to the right of the Dedicated Resources field to open the Dedicated Resources window.

  5. Select Schedule this workload with dedicated resources (guaranteed policy).

  6. Click Save.
