Abstract:
In an example embodiment, a hypervisor exposes a first guest device to a first virtual machine. The hypervisor exposes a virtual host device and a pass-through device to a second virtual machine. The hypervisor maps a first memory and a second memory into the second virtual machine at a first base address register and a second base address register associated with the virtual host device and pass-through device. The hypervisor sends a mapping from the first virtual machine to the second virtual machine. The hypervisor sends a first address of a first ring of the first guest device and a second address of a second ring of an assigned device to the second virtual machine.
