Virtualbox 5.1 just launch few days ago. I can’t wait to test those awesome feature from version 5.1.
But if you have RTR3InitEx failed with rc when you start your virtual machine. My solution is uninstall Virtualbox 5.1 and reinstall again.
Vagrant not support Virtualbox 5.1
I have problem with vagrant 1.8.4. However simple solution can be solved using the following link:-
If you have the following error:-
There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.
Command: [“startvm”, “f730c1fd-fe57-4c50-8708-e1d6d034b7f5”, “–type”, “headless”]
Stderr: VBoxManage.exe: error: Nonexistent host networking interface, name ‘VirtualBox Host-Only Ethernet Adapter #2’ (VERR_INTERNAL_ERROR)
VBoxManage.exe: error: Details: code E_FAIL (0x80004005), component ConsoleWrap, interface IConsole
Run vagrant reload may solved your issue.
