This is weird, though. We have libxml2-devel as a 'general' dependency
in devstack[0]. I checked and the package is still there. I'll give
this a try on a fresh f20.

Oslo's incubator install failed because of the missing lxml
dependency, which resulted in the oslo-rootwrap entry_point not being
created. This caused cinder configuration process to fail after trying
to use the not existent oslo-rootwrap bin.
