For Desktop, you may want to consider install VirtualBox Guest Additions by selecting Devices -> Install Guest Additions.

When creating an appliance make sure to compact properly, by running the following commands on the VM:

rm cs-course_vm.sh
dd if=/dev/zero of=fillfile bs=1M
rm fillfile
history -c
sudo shutdown -h now

Then, on the host side:

VBoxManage modifyhd /path/to/VDI --compact

Also, you may want to enable ssh access by:

VBoxManage modifyvm "cs-course_vm" --natpf1 "guestssh,tcp,,2222,,22"
ssh -p 2222 cs102@127.0.0.1

Optionally, you may add the following tweaks:

• Enable copy/paste between host and guest machines by selecting: Devices -> Shared Clipboard -> Bidirectional
• Install Eclipse
• Terminal Preferences: Edit -> Profile Preferences:
  • General -> [ ] Terminal Bell
  • Scrolling -> [x] Unlimited

Eclipse Installation Guidelines:

1. Head to the Eclipse Download page.
2. Download the appropriate version of Eclipse
3. Run the following script to install and setup Eclipse

#Extract files
sudo tar zxvf eclipse-*.tar.gz -C /opt/
#Change ownership to root
sudo chown -R root:root /opt/eclipse/
#Add a symlink for the executable to /usr/bin
sudo ln -s /opt/eclipse/eclipse /usr/bin/

#Create menu entry
echo "[Desktop Entry]" | sudo tee /usr/share/applications/eclipse.desktop
echo "Name=Eclipse IDE" | sudo tee -a /usr/share/applications/eclipse.desktop
echo "Comment=Integrated Development Environment" | sudo tee -a /usr/share/applications/eclipse.desktop
echo "TryExec=/opt/eclipse/eclipse" | sudo tee -a /usr/share/applications/eclipse.desktop
echo "Exec=/opt/eclipse/eclipse" | sudo tee -a /usr/share/applications/eclipse.desktop
echo "Icon=/opt/eclipse/icon.xpm" | sudo tee -a /usr/share/applications/eclipse.desktop
echo "Categories=Development;IDE;Java;C;C++" | sudo tee -a /usr/share/applications/eclipse.desktop
echo "Terminal=false" | sudo tee -a /usr/share/applications/eclipse.desktop
echo "Type=Application" | sudo tee -a /usr/share/applications/eclipse.desktop
echo "StartupNotify=true" | sudo tee -a /usr/share/applications/eclipse.desktop

Finally, if you wish to alter the launcher to include eclipse:

gsettings set com.canonical.Unity.Launcher favorites "['gnome-terminal.desktop', 'nautilus-home.desktop', 'eclipse.desktop', 'gedit.desktop', 'gvim.desktop', 'emacs23.desktop', 'google-chrome.desktop', 'firefox.desktop', 'filezilla.desktop']"
