Abstract: Embodiments described herein relate to adjusting performance of a virtualization layer to reduce underutilization of a physical device. The virtualization layer virtualizes access to the device for a VM. When a guest in the VM makes a request to a virtual device, the virtualization layer and the device work together to satisfy the request.

The software/CPU time relative to the device time serves as a basis for deciding whether to increase or decrease processing capacity of the virtualization layer (or a component thereof), thus reducing underutilization of the device and over-provisioning of processing capacity to the virtualization layer.
