Thanks for the detailed report! Indeed, the networking capabilities are a bit limited with the kernel modules being absent now. Standard NAT works fine, the rest (NAT network, bridged adapter) would need to be done manually (e.g., using tun/tap). Sorry for the inconvenience, we will make sure to include those limitations in the readme!

Will there ever be a release that will support other network flavors (bridged, etc) as the stock VBox? Thanks

Currently, we are focusing on the virtualization part of things. At this point, we don't have plans to work on the UI and configuration side. If there is a concrete need for this beyond what's already possible with outside scripting, feel free to get in touch with my colleagues at https://cyberus-technology.de/contact.

We should eventually take a closer look at the VBOX_WITH_INTNET_SERVICE_IN_R3 config that is used on Darwin to provide more options here without the custom kernel modules.

Just to let everyone know, we have now included more information in the readme. Feel free to have a look and let us know if that clarifies things!
