1. An apparatus to provide support for multiple virtual computing machines, the apparatus comprising:

  • a platform manager configured to support multiple guest operating systems;

    a virtual machine manager (VMM) driver of the platform manager;

    a TCP/IP (transmission control protocol/internet protocol) stack of the platform manager, wherein the VMM driver interfaces a top of the TCP/IP stack;

    a first guest operating system supported by the platform manager; and

    a TCP (transmission control protocol) offload pseudo driver module of the first guest operating system, wherein the TCP offload pseudo driver module is to pass data between a component of the first guest operating system and the VMM driver,wherein the VMM driver is configured to transfer the data between the top of the TCP/IP stack and the TCP offload pseudo driver module of the first guest operating system without changing a level of abstraction of the data.
