VDI

I have one Xubuntu 12.10 64 bit Virtualbox VM on a Windows 7 64 bit host. It has one dynamic allocated hard disk with VDI format with maximum capacity of 20GB.

If I use a command df -h in the VM I get that 5.3GB are in use in th main partition. I have only 2 partitions, one for the ext4 hard disk and another with 512MB of swap. I have no snapshots.

The VDI file of this VM has 10.7GB. It is normal this difference of space? It is caused because the VDI format?
