[Bug 1447030] [NEW] RBD volumes created with reversed stripe_unit and stripe_count parameters

[Florian Haas]

Public bug reported:

Copied from upstream bug at
https://bugzilla.redhat.com/show_bug.cgi?id=1092208:

When creating an RBD volume with 'virsh vol-create-as', the newly
created volume gets a stripe unit of 1 byte and a stripe count of
4194304. This results in an RBD volume which is unusably slow (in my
tests, it took over 30 minutes for GRUB to load in an affected guest).

This bug has been fixed upstream for libvirt 1.2.4, but the fix has not
been backported for trusty-updates. This means this functionality is
broken and unusable in the current LTS.
