This issue is proposing the idea of exposing VSOCK using AF_UNIX as the
host backend, in a manner that's compatible with that used by firecracker
and cloud-hypervisor:

Recent versions of Windows support AF_UNIX these days, so hopefully that
would be satisfactory as an approach ?

With regards,
Daniel
