This project will complete the current bhyve VirtFS/9p work with a roadmap for feature competitiveness with QEMU/KVM and Windows WSL2.

I remember getting excited about this back in late 2016 when I saw this newsgroup message by Jakub Wojciech Klama from earlier that year. If we could have this in bhyve, I would be unreasonably happy.

For those unfamiliar, at a high level VirtFS allows you to pass through folders directly into virtual machines from a host, rather than dealing with generic NFS or Samba/CIFS. This paper by members of IBM’s Linux Technology Centre goes into great detail explaining the motivation behind the system, and its implementation. I’ll try and blog more about it.
