Troubleshooting: failed install of VM

Vagrant install of "Mining the Social Media" virtual machine. https://github.com/ptwobrussell/Mining-the-Social-Web-2nd-Edition

Needed to apply two fixes for the install to work. During "vagrant up" got message: Failed to mount folders in Linux guest

	Use the following URL to find answer:

Run this on guest (i.e. after you ssh into vbox via vagrant ssh )
    sudo ln -s /opt/VBoxGuestAdditions-4.3.10/lib/VBoxGuestAdditions /usr/lib/VBoxGuestAdditions
    Then run "vagrant reload" to correctly mount the folders.

Pasted from <http://stackoverflow.com/questions/22717428/vagrant-error-failed-to-mount-folders-in-linux-guest>

Install still failed to start. Solution is to run "vagrant provision" after the reload above. This is because of a change in vagrant to not automatically run provision each time. https://github.com/ptwobrussell/Mining-the-Social-Web-2nd-Edition/issues/146

NOTE: Try "vagrant up --provision" instead of reload and provision listed above.
