== Zeroing an encrypted disk == | |||
If you use disk encryption in the guest OS then zero'ing out the disk won't help. | |||
The reason is that a good disk encryption scheme will write out random data to the disk when you write out zero's. | |||
In other words, if you have enabled full disk encryption in the guest then you can not shrink the disk anymore as there is no space to reclaim. | |||
