[SOLVED] VBoxManage: error: Failed to create the host-only adapter
Dec 6, 2020
A different error could be VirtualBox “Kernel driver not installed (rc=-1908)” Error on macOS.
After cloning old machine into new Macbook Pro when I tried to start my VirtualBox and I run into fallowing error.
Solution: unblock VirtualBox in Security & Privacy:
If you cannot see “Allow” button you would have to run following command:
sudo /Library/Application\ Support/VirtualBox/LaunchDaemons/VirtualBoxStartup.sh restart
Once you run the command open Security & Privacy again and you will see the “Allow” button. Once you clicked “Allow” button run follow above mentioned command again, this time it should be executed successfully:
sudo /Library/Application\ Support/VirtualBox/LaunchDaemons/VirtualBoxStartup.sh restart
You’re all set. Happy hacking!
