Description Dan Kenigsberg 2016-06-08 11:22:45 UTC

RHEV-3.3 introduced https://www.ovirt.org/develop/release-management/features/storage/diskalignment/ to let users verify whether their guests have sane partition alignments.

This is important for performance of old guest OSs (mainly Windows).

The feature depends on libguestfs-tools-c, which is not delivered on RHEV for PPC. The feature is not really interesting on PPC, as we are unaware of PPC-compatible OS that creates misaligned partitions.

The bug is opened only for documenting this fact.

Comment 1 Lucy Bopf 2016-06-30 06:58:45 UTC

Updating the doc text for inclusion in the Release Notes.

Leaving this bug open for now to assess whether any further docs changes are required.
