Description Idan Shaby 2017-01-22 15:31:40 UTC 
Description of problem:
Sparsifying a disk with enabled wipe after delete on block storage domain when the domain does not support the property that discard zeroes the data causes unwiped data to be discarded, and therefore should be blocked.

Version-Release number of selected component (if applicable):
589412437fbd19cd59c08570dccaf2313cb5b539

How reproducible:
100%

Steps to Reproduce:
1. Create a block storage domain on an underlying storage that does not support the property that discard zeroes the data (see [1] for more info).
2. Create a vm.
3. Create a disk for the vm on that storage domain.
4. Try to sparsify this disk.

Actual results:
works

Expected results:
Should not work.
