Abstract
A computing device executing a virtual machine and a hypervisor that manages the virtual machine receives a data packet that is addressed to the virtual machine. The computing device writes the data packet to a buffer in a shared memory. The computing device maps the buffer to a memory of a virtual appliance that is hosted by the hypervisor to enable the virtual appliance to operate on the data packet without making a copy of the data packet. The computing device provides the data packet to the virtual machine after the virtual appliance has operated on the data packet.
