When deploying the bootstrap vagrant-onap projects with 'vagrant up', the provisioning can fail if the virtualbox guest additions of the host are a newer version and the vagrant-vbguest plugin is installed.

This is because a newer version of the virtualbox guest additions are installed onto the /opt directory of the guest.  The bootstrap Vagrantfile mount's ./opt from the host machine onto /opt of the guest as well.  Once this occurs, subsequent mounts of other shared directories fail and the provisioning process fails.

It has been observed that uninstalling the vagrant-vbguest plugin avoids this problem.
