vagrant upをすると稀に下記のエラーが表示される

$ vagrant up Bringing machine ‘manage’ up with ‘virtualbox’ provider… [manage] Clearing any previously set forwarded ports… [manage] Creating shared folders metadata… [manage] 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

この場合は下記コマンドを実行してVirtual Boxを再起動したら直ります。なぜ発生するかの原因は不明ですが・・・。

$ sudo /Library/StartupItems/VirtualBox/VirtualBox restart
