Editing Running madagascar on a virtual machine (section)

=== Installing guest additions ===
I will describe the steps I followed for a successful install.  You may find a better or more efficient approach.<br>

If you encounter the "USB error" described in the previous section, follow these instructions to install "guest additions".<br>

In the virtualBox window click on the system "ub2bg", then click the yellow cog.  Click ports, and usb.  Make sure the  "enable USB Controller" is NOT checked.  Click OK, then double click the "ub2gb" system to start it.  It will take a few minutes to start.<br>
Either the password (seismic) to complete the login.<br>
<br>
On the top click Devices then insert guest addition CD.  This will make a virtual CD available.  On a windows host system autorun.sh will automatically run.  On Linux or Mac you must manually start the script:<br>
Double click the new CD icon on the desktop, which will pop up a file manager window, which you can close.  The CD will now be mounted.  You can verify this with:<br>
df<br>
On my system /media/seismic/VBOXADDITIONS_5.1.18_114002 is mounted.  Change to that directory, list the directory,  and run outrun.sh:<br>
cd  /media/seismic/VBOXADDITIONS_5.1.18_114002<br>
ls<br>
sudo ./autorun.sh<br>
Enter the password (seismic) when prompted.<br>
A window will pop up and you need to wait until installation is compete.  Press Return to close the window...<br>
Change to your home directory, and search history for an apt-get that will install another part of guest additions:<br>
cd<br>
history | grep apt-get<br>
Copy and paste the next line into the terminal:<br>
sudo apt-get install virtualbox-guest-dkms -y<br>
Sometimes I received an error saying unable to obtain lock, but repeating the commend ran just fine.<br>
When the terminal says DKMS: install complete, close the whole virtual system window using the 'X" in the window frame.  You do not want to save the machine state, or just power off the system (that is like pulling the plug or pushing the power button on a real system.  You want to reboot the system, so make sure the "Send the shutdown signal" is selected and click the  "OK" button.  Restart the system by double clicking the "ub2bg" system in the "VirtualBox manager" window.<br>
