Transparent deployment of intermediary manager into guest operating system network traffic

摘要

A technique transparently deploys an operating entity (OE) into a network data path of a virtualized computing environment that includes a guest operating system (OS) running in a virtual machine instance (VMI) of a virtual data center (VDC). The OE is embodied as an intermediary manager, e.g., a meta-hypervisor (metavisor), of a computing cell within the VMI that includes the guest OS and associated applications. The computing cell is layered over a hypervisor which manages system resources of the VDC in an arrangement such that the metavisor is disposed between the hypervisor and guest OS, and operates transparent to the guest OS. The transparent deployment technique involves a set of conditional tests and actions embodied as modules of the metavisor that is applied to examine network packet traffic exchanged over the network data path and that operates to make the presence of the metavisor within the network data path “invisible” (i.e., transparent) to the guest OS, i.e., so that the guest OS is unaware of the presence of the metavisor.
