If you want to see an example of a branch new vhost-user daemon being
built up from scratch see my recent virtio-rpmb series. The first few
patches of in-QEMU code will be the same boilerplate either way I think:

This really clears everything about vhost-user daemons. Thanks a lot.

I am currently looking at how the sound subsystem is implemented in QEMU.

If I can recreate something similar for the vhost-user daemon,

I'll make it a vhost-user daemon. Else I will implement

it as an in-QEMU device. Either ways, I'll provide an implementation

plan with a loose timeline tomorrow.

I will start writing the code for the device from tomorrow.
