   * On some laptops the hardware feature that allows virtual machines to work efficiently (Intel VT-x) is disabled. If while importing or starting the VM you get error messages like 'This host supports Intel VT-x, but Intel VT-x is disabled'​ then reboot your computer, enter the BIOS settings, and make sure the '​VT-x'​ setting is set to '​Enabled'​. As the setting can be called slightly differently for different laptops, please let us know if you need help with this problem.   * On some laptops the hardware feature that allows virtual machines to work efficiently (Intel VT-x) is disabled.

   * The virtual machine by default allocates 2 CPU cores and 4 GB of RAM. If your laptop has less than 8 GB of RAM or less than 4 CPU cores, you might want to reduce these numbers (e.g. to 1 CPU core and 2 GB of RAM). You can do so by right-clicking on the CIDER2018 virtual machine icon in VirtualBox, and then go to the ''​Systems''​ tab. The amount of RAM can be set in the ''​Motherboard''​ panel, and the number of CPU cores can be set in the ''​processor''​ panel. You will have to shutdown the virtual machine in order to change these settings.   * The virtual machine by default allocates 2 CPU cores and 4 GB of RAM.

 +  * On some laptops the shared folder will not allow writing into the shared folder inside of the virtual machine. This can be circumvented by becoming the superuser inside of the virtual machine. To move an example file called '​test'​ into a shared folder named '​shared_folder'​ you will have to use the following commands:
 +    * ''​su cideradmin''​ \\ (when asked for the password type ''​cideradmin''​)
 +    * ''​sudo mv test shared_folder/''​ \\ (when asked for the password type ''​cideradmin''​)
 +    * ''​exit''​
