I hope so :)

Yes, I read somewhere on Docker that only a specific (new enough) OS
version is needed for the host. For the guest I was basing my guess on
    https://github.com/kholia/OSX-KVM
which specifically mentions just 10.11-10.13 and in addition needs
different instructions for installing 10.13 as a guest.

I'm aware that it's legal to virtualize macOS on mac hardware, it's
just not 100% clear to me that all of the steps involved in setting up
libvirt images are 100% OK. (Can those same images be used on Linux
unmodified? If so, I would at least imagine that preparing them
requires the knowledge of a special "key" that's available in the
above mentioned repo. I don't know though.)
