To improve performance, you can dedicate node resources, such as CPU, to a virtual machine.

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.


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

  • The virtual machine must be powered off.

Enabling dedicated resources for a virtual machine

You can enable dedicated resources for a virtual machine in the Details tab. Virtual machines that were created by using a Red Hat template or the wizard can be enabled with dedicated resources.

  1. Click WorkloadsVirtual Machines from the side menu.

  2. Select a virtual machine to open the Virtual Machine tab.

  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.
