Fixing a Vagrant "hostonlyif" error
tl;dr: Load the correct module:
sudo modprobe vboxnetadp
I recently came across an article about LXC, Exploring LXC Networking, which used Vagrant to get a development machine up and running.
I wanted to try it, but stumbled across a problem for which I mostly found the OS X solution:
sudo /Library/StartupItems/VirtualBox/VirtualBox restart
But this does not work on Linux. I finally found the working solution in the post Resolve a hostonlyif create error with vagrant. So for full documentation I repeat it here again.
I used the following Vagrant file:
Vagrant.configure(2) do |config| config.vm.box = "precise64" config.vm.box_url = "http://files.vagrantup.com/precise64.box" config.vm.provision :shell, :inline => pkg_cmd # Create a private network config.vm.network :private_network, ip: "10.0.4.2" # Create a public network config.vm.network :public_network end
vagrant up I got the following error:
$ vagrant up Bringing machine 'default' up with 'virtualbox' provider... [default] Clearing any previously set forwarded ports... [default] Clearing any previously set network interfaces... There was an error while executing `VBoxManage`, a CLI used by Vagrant for controlling VirtualBox. The command and stderr is shown below. Command: ["hostonlyif", "create"] Stderr: 0%... Progress state: NS_ERROR_FAILURE VBoxManage: error: Failed to create the host-only adapter VBoxManage: error: VBoxNetAdpCtl: Error while adding new interface: failed to open /dev/vboxnetctl: No such file or directory VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component HostNetworkInterface, interface IHostNetworkInterface VBoxManage: error: Context: "int handleCreate(HandlerArg*, int, int*)" at line 68 of file VBoxManageHostonly.cpp
Loading the right kernel module helped:
sudo modprobe vboxnetadp
vagrant up worked as expected and the machine was accessible via SSH:
