[Bug 1285197] Re: growpart failed in ppc64el guest

[Scott Moser]

Well, for the first time in quite a while, I saw this on a 20140407 image.
There were other things changed though, this system:
 * had a 120G root (versus normal ~10G)
 * is a power 8 host
 * had 4 cores not 2

relavent output (cleaned from /var/log/cloud-init.log):
