VBoxNetAdpCtl outright doesn't work/can't create host-only network

[jchv]

Bug Description

Attempting to create a host-only network gives the following error:

I understand that networking is not the priority here, but it's unclear how one can even create a host-only network. Is it possible? I have been spelunking the Virtualbox source code to no avail trying to figure out how this might work in driverless mode. I would be very grateful if I could get some pointers!

The message about networking in the README doesn't imply that host-only networking can't work, but if it can't right now, maybe it would be good to explicitly add that to the note about networking. :(

How to Reproduce

Try to create a host-only network in the UI.

You can also reproduce it directly via the VboxNetAdpCtl command:

$ VBoxNetAdpCtl add
VBoxNetAdpCtl: Error while adding new interface: failed to open /dev/vboxnetctl: No such file or directory

VM configuration

(Not applicable.)

Unfortunately, it's not possible right now and we currently don't have funding to work on a good solution for bridged and host-only networking ( see #25 ).

Since this is a question that we get a lot from the community, we just enabled github-sponsors . If we get sufficient momentum, we would be able to provide a nice networking solution that works identical to vanilla VirtualBox.
