If `modprobe vhba` doesn't work, that means, that `vhba.ko` isn't properly
installed to `/lib/modules`. Does `insmod /path/to/vhba.ko` work?

Anyone have a step by step procedure to get vhba to modprobe ?

As Rok said, that depends on your distro. E.g. Debian has a thing called
`module-assistant` https://wiki.debian.org/Modules

As for further configurations, while not exactly step-by-step, you can have
a look at NixOS' cdemu packaging for an overview of all that's necessary.
In the OS - level installation:
https://github.com/NixOS/nixpkgs/blob/43d4f07bf1144d6eb20975c956c7cc7bc643ea6e/nixos/modules/programs/cdemu.nix#L38
you can see the kernel module, udev rules, and that dbus needs to find
`cdemu-daemon`'s `share/dbus-1/services/net.sf.cdemu.CDEmuDaemon.service`
descriptor file, in order to connect daemon and UIs. See also
https://nixos.org/nixos/options.html#services.dbus.packages

Here are the corresponding package build files, but you already got it to
compile anyway ..
