Abstract
The disclosure provides a method of performing a workload on a virtual machine (VM) executing on a host comprising one or more physical central processing units (pCPUs) is provided. The method further includes setting a quality of service (QoS) metric associated with the VM, the QoS metric indicating a time period. The method further includes setting a bandwidth metric associated with the VM, the bandwidth metric indicating a percentage. The method further includes allocating by a central processing unit (CPU) scheduler to a virtual CPU (vCPU) of the VM one of the one or more pCPUs periodically every time period, wherein for every time period the one of the one or more pCPUs is allocated to the vCPU for a duration that is the percentage of the time period based on the QoS metric and the bandwidth metric. The method further includes executing the workload on the virtual machine with the vCPU according to the allocation of the one or more pCPUs.
