oVirt includes an option to wipe a disk after it is deleted to securely erase the disk image.
To perform this we do a simple overwrite, however we may need to perform a more secure erasure for security and compliance reasons. (eg. PCI compliance etc)
We should mirror the work performed by the libvirt team in which they provide a number of algorithms to use when wiping an image.

This is an RFE targeted for 4.1.
Idan is working on it, but the work is being done on the code, not on bugzilla, so there aren't too many updates here.
Reducing priority to HIGH to avoid nagging emails from nagging whines.
Moving to MODIFIED as BZ #1367806 upstream is already being tested.
Yaniv, please note that Bug 1367806 only adds blkdiscard as an option to wipe volumes, but it is not the default option.
BZ 1475780 is responsible for making it the default wiping method.
Yaniv - please see comment 27 (was missing a needinfo, probably). I think this should be moved back to ASSIGNED.
ATM, this is an available via optional configuration. Setting it to the default is pending the scale's team help on verifying it's usefulness/safety.
