Linux based OS that is dedicated to running a MacOS Virtual Machine

Hello /r/Hackintosh,

I was wondering if there was some sort of Linux based or lightweight OS that could act as a bridge to launch Virtual Disk images. So Upon launching the OS, it would not boot into Linux but launch VirtualBox instead (or some other VMWare program) that would launch MacOS Catalina in Virtualware format.

I am looking to alternative to Hackintoshing and I don't have enough info on the topic to know where to start. I don't know if such a thing exists or if I'm using the incorrect search terms.

Thank you.
