Class Method Details

.register(hook) ⇒ Object

Vbguest plugin updates GuestAdditions for VirtualBox before ‘::Vagrant::Action::Builtin::SyncedFolders’ and therefore needs to be registered. Prepending Vbguest hook ensures that, but this is done only with Vbguest plugin and VirtualBox provider. In other cases the behavior is unchanged.

.setup_logging ⇒ Object

This sets up our log level to be whatever VAGRANT_LOG is for loggers prepended with ‘vagrant_registration’
