Description Allon Mureinik 2016-06-09 14:30:49 UTC

Description of problem:
As described on bug 1343938, libguestfs-tools-c which provides the underlying capability for scanning alignment is not shipped on PPC.
GetDiskAlignmentCommand#validate() should check this and fail gracefully if that is the case.

Version-Release number of selected component (if applicable):
Any RHEV for Power build

How reproducible:
100%

Steps to Reproduce:
1. Set up a single hypervisor deployment on power
2. create a disk
3. run scan aligment

Actual results:
Ugly failure

Expected results:
Nice validation message
