 ### Resizing the virtual machine screen
 
 If the virtual machine loads and you find it is not an appropriate size, you can find the size that works for you by doing the following:
 
 1. In your VirtualBox VM menu, go to **View > Virtual Screen 1 > ...**. You will see different scaling options; select the one that best suites your screen.

 Once the virtual machine loads, Eclipse will open. In Eclipse, there will be 8 projects loaded on the left side in the Project Explorer. Seven of the projects are from the [Defects4J](https://github.com/rjust/defects4j) defect benchmark; these projects are labeled *Defect_0_Training*, *Defect_1*, *Defect_2*, *Defect_3*, *Defect_4*, *Defect_5*, and *Defect_6*. The eighth project is *Holmes*.
