I have a virtual machine with VDI disk configured as a Dynamically Allocated with maximum of 20 gigabytes.
Guest OS (Linux Mint) reports usage of 10.7 GB.
Why actual VDI size is 16.5 GB, instead of 10.7? How to compact it?
I've performed disk cleanup as described here (I used pv & dd method because other one just hanged my guest os). Disk shrink but just a little from 17 GB to 16.5 GB.
