Abstract
A para-virtualization method is provided. The method comprises implementing a virtual machine (VM) for guest software running on first host software. In response to a privileged instruction, the guest software causes a first VM exit. If the first host software is not running directly on hardware, the privileged instruction is managed without causing a second VM exit. Otherwise, the privileged instruction is managed normally.
