Your computer should meet certain criteria for best performance when creating and running virtual machines in Boxes. These requirements are specified by the vendors of the operating systems. Boxes automatically allocates resources to virtual machines based on vendor recommendations. When such information is unavailable to Boxes, it allocates the following:
20 GB of maximum storage space.
This does not mean that Boxes will allocate 20 GB of space when creating the virtual machine. The actual disk space used by Boxes will be less than (or in worst case, equal to) the disk space used by the virtual machine itself.
500 MB of RAM.
Boxes performs best if your computer processor supports hardware virtualization extensions and these are enabled in the system BIOS.
It is also recommended that you have at least 8GB RAM and 20GB of free disk space on your computer to efficiently run Boxes.
