After entering the PIN into your CernVM's login screen (preceeded by the hash symbol), your CernVM reboots to display a graphical CernVM login screen. Meanwhile, the CernVM Pairing web page has updated to display the message,

Your vm is now paired with CernVM Online! Upon logging in to your new CernVM with the username
gridppand the password
gridpp, you are presented with the CernVM desktop.
Accessing your local machine's hard disk from you CernVM: You can access (from the command line or otherwise) folders on your local machine's hard disk on the GridPP CernVM. So (for example) if you're using VirtualBox with the Shared Folders functionality, after adding the folders you want access to via the VM's Settings and rebooting the VM you'll do something like this:
$ sudo usermod -a -G vboxsf gridpp [sudo] password for gridpp: # Enter 'gridpp' here.
before loggin out and logging in again. You'll then be able to access the folders you specified.
$ cd /media/sf_alovelace/ # Shared Folder "alovelace" $ ls punch-card-01.dat dad-poem-001.txt my-poem-005.txt
