After a virtual machine is used for a long time, it will find that the virtual hard disk is getting bigger and bigger. However, after reading the system commands in the virtual machine, the occupied space is far from the size of the virtual hard disk, this is unpleasant and inconvenient for sharing Virtual Machine images. Virtualbox does not seem to provide a graphical interface for us to compress the virtual hard disk size, but it can be achieved through the command line. According to actual te
