The packages in this directory comprise most of the code used to build the guest side agent for Linux Hyper-V containers on Windows (LCOW). The guest agent is designed to run inside a custom Linux OS for supporting Linux container payloads. It's a process that is designed to be connected to from a host machine to carry out requests for running containers in the Linux guest.
The two binaries of importance that are built from this code are the main guest agent that facilitates communication between the host and guest and a generic tools binary for additional functionality for device scenarios.
As most of the rest of the repository is designed in part to run on Windows, the guest package tries to serve as a separation between the two. Any guest side LCOW specific feature work should end up here.
