Non-Linux VMs should have an option to enable Apple Virtualization

With the recent release of OpenBSD 7.9, [Apple Virtualization is supported](https://github.com/openbsd/src/commit/dbd3071e8d823c9488101fe08c333e539a493928) in the stable release. Since other, non-Linux OSes can now run under Apple Virtualization (more BSDs are likely to adopt this feature as well), it would be nice to have an option to enable this if we know that the guest OS supports it.
