Remove VirtualBox support in release 2.0 #1788
Description
I can't find a good reason to keep VirtualBox in netlab:
- I haven't seen a request to implement something for VirtualBox in years, and we only support it for a few devices.
- VirtualBox on MacOS no longer makes sense. The last x86 product was discontinued almost two years ago.
- WSL runs on Windows 10 Home edition for ~ 4 years (https://www.reddit.com/r/bashonubuntuonwindows/comments/j5c0xd/is_wsl_2_available_on_windows_10_home/)
Obviously, one could still use VirtualBox with netlab release 1.9.x (and I have no problems backporting critical fixes into a -postX release), but it would be gone from 2.0
