Lab environments

You must complete all labs on the given virtual machine (VM). To install the virtual machine on your computer, take the following steps.


In case you face a problem related to importing the VM, please check the following.

Windows OS

The following steps are for Windows Machines:
  1. Reboot your machine
  2. During the reboot process, and before the Windows Logo appears, keep pressing  ( F2 or F1 or F10 or F8 or Delete or ESC, sometimes it is different key. Pay close attention to the initial screen when you press the power button. It will say which key to press to get to the Setup menu.).  But act quickly. If the Windows starts then go back to step 1.
  3. This will open the BIOS menu
  4. The menu will be very different depending on BIOS version and processor type. But navigate till "Security" menu.
  5. Ensure that VT-x (for Intel Processors) or AMD-v (for AMD processors) are enabled.  You will have something similar to Figure 1 below.
  6.  Save and exit the BIOS
  7. The machine will reboot.
  8. Start virtualBox --> select the VM (cso) from the left handside. --> go to settings of the VM --> System --> Acceleration --> ensure that "Enable VT-x/AMD-v" is activated

If you are still facing a problem, please send it to the course mailing list and we will do our best to help.
