libvirt ships with virt-install which also allows for quickly creating and auto-installing Windows and many Linux distributions. I haven't tried it with mac.

Here's a recent example with Alma Linux:

  $ virt-install --name alma9 --memory 1536 --vcpus 1 --disk path=$PWD/alma9.img,size=20 --cdrom alma9.iso --unattended

Then you go for a coffee, come back and have a fully installed and working Alma Linux VM. To get the list of supported operating systems (which varies with your version of libvirt), use:

  $ osinfo-query os
