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: https://gitlab.com/qemu-project/qemu/-/issues/2095 Recent versions of Windows support AF_UNIX these days, so hopefully that would be satisfactory as an approach ?
