Abstract
In an example embodiment, a hypervisor exposes a first guest device to a first virtual machine and a second guest device to a second virtual machine. The hypervisor exposes a first virtual host device and a second virtual host device to a third virtual machine. The hypervisor maps a first memory and a second memory into the third virtual machine at a first base address register and a second base address register associated with each virtual host device. The hypervisor sends a first mapping from a first virtual machine and a second mapping from a second virtual machine to the third 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 the second guest device to the third virtual machine through the respective virtual host devices.
