 Your new VPP Device virtualbox machine will be created and configured.
 Master branch of csit project will be cloned inside virtual machine into
-      /home/vagrant/csit folder.
-Once the process is finished, you can login to the box using:
-      vagrant ssh
 
-From within the box run the tests using:
-      cd /home/vagrant/csit/resources/libraries/bash/entry
-      ./bootstrap_vpp_device.sh csit-vpp-device-master-ubuntu1804-1n-vbox
