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
"Error while executing action: Cannot scan alignment Virtual Disk. Alignment scan is not supported on PPC." nice message displayed on 4.1.0.4-0.1.el7
