I have Kubuntu as a host system and ubuntu as a guest system on Virtual Box. Virtual hard drive was created with flag "Dynamically allocated storage" so I assumed that size of the storage should grow with system requirements.
Now I'm checking on my virtual system:
$df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 11G 6.5G 3.7G 65% /
and that is real size of virtual disk on host system
$ls -s Ubuntu.vdi -h 12G Ubuntu.vdi
- how to reduce actual size to 65%?
