Abstract: A virtualization system may receive, by a physical hardware device driver of a kernel of a guest OS of the virtualization system and from a process of the guest OS, one or more control messages to control a physical hardware device. The virtualization system may determine, by the physical hardware device driver and based on the second-type physical hardware device address included in the one or more control messages, a first-type physical hardware device address associated with the physical hardware device. The virtualization system may update, by the physical hardware device driver, the one or more control messages to include the first-type physical hardware device address, and may send, by the physical hardware device driver and to an emulated physical hardware device of a hypervisor of a host OS of the virtualization system, the one or more control messages.
