Unable to run movit.

edit

I Just Installed ros on ubuntu 14.04 running as a guest on my virtual box(windows as host), by following the guidelines given on the installation page. After that I installed movit to run pr2 robot on it. on starting the program by following command roslaunch pr2_moveit_config demo.launch

the process starts and then stops with following error
