Implement 9P File Sharing for Windows hosts

Motivation

File sharing is a critical capability for many software development and IT operations workflows. Allowing developers to easily access and collaborate on shared assets, such as source code, configuration files, and other project resources. Implementing a robust file sharing solution can improve productivity, facilitate version control, and enable seamless collaboration across different operating systems and environments.

Objectives

Add 9P server functionality to a Windows host system to enable file sharing.
Implement 9P client functionality on a RHEL virtual machine to access the shared files from the Windows host.
Ensure reliable and secure file transfer between the Windows host and the RHEL VM using the 9P protocol.
