Here is one good topic which I already know about. Virtual Box virtual disks' sizes! https://superuser.com/questions/1096549/file-based-dynamically-allocated-hard-disk-on-linux
Two questions (stress on [1]): [1] VirtualBox allows you to create VDI, VMDK, and VHD types of hard-disks that can be either fixed- or dynamically-sized. Is there any way to make a file-based dynamically-sized hard-disk for use by a Linux host OS? (although I never the found way how to dynamically shrink VDI VD, the expansion is obvious) [2] Is it possible to employ any of these three types of file-based, dynamically-sized hard-disks outside of VirtualBox, on a Linux host OS?
