Although Phyllome OS would like to support as many operating systems as possible, it mainly focuses on modern, UEFI-compatible operating systems that are shipping with at least some support for [virtio devices](/virt/lexicon#paravirtualization).
As of today, without accounting for Linux distributions, there are dozens of production-ready operating systems.
That being said, there are two families of operating systems that dominate this space, the Unix family and the Windows family. Everything else will be categorized as independent.
> Support for guest systems differs widely. In general, free and open-source operating systems such as Linux distributions are better supported than proprietary operating systems.
