Abstract
Access to a physical device associated with a computing system can be shared with multiple virtual machines by delegating control of the physical device to a primary virtual machine (PVM). In some aspects, a virtual machine monitor (VMM) of the computing system can generate a hardware description that describes the physical device. The VMM can initiate the PVM, which can use the hardware description to acquire control of the physical device from a host kernel of the computing system. The VMM can delegate control of the physical device from the host kernel to the PVM. After control of the physical device is delegated to the PVM, the PVM is configured to perform a device sharing process to share access to the physical device with the SVM.
