the hard usage from inside the vm is

Code: 
peiman@digidoc:~$ df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            3.9G     0  3.9G   0% /dev
tmpfs           798M  956K  797M   1% /run
/dev/sda2       629G  7.7G  590G   2% /
tmpfs           3.9G     0  3.9G   0% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
tmpfs           3.9G     0  3.9G   0% /sys/fs/cgroup
/dev/loop0       89M   89M     0 100% /snap/core/7270
/dev/loop1       90M   90M     0 100% /snap/core/7917
tmpfs           798M     0  798M   0% /run/user/1000

When discard (trim) is not run inside the VM to free empty blocks, the file will grow till its full capacity.
