vagrant 'hostonlyif' create not working

Question

I\'m trying to do a vagrant up on a box, and I get the following error.

INFO interface: error: There was an error executing the following command with VBo

Answer 1

I didn't see the version of VirtualBox you are running in your question but for version 4.2.x the command listed by the previous answers:

sudo /Library/StartupItems/VirtualBox/VirtualBox restart

should fix your issue. If you are running 4.3.x though the equivalent to this command is:

sudo launchctl load /Library/LaunchDaemons/org.virtualbox.startup.plist

This will also restart the VirtualBox services and should fix your issue.

As a side note I have run into the issue where running that command will silently fail and cause VirtualBox to emit the same behavior you described. This is usually caused due to a VM still being active and can usually be resolved by suspending or destroying your vagrant instances or other VMs and rerunning the command.
