I thought I remembered something about it, but couldn't find it in the
archives.  First, about newton, it's dead (2017-10-11).  Next, about ocata,
it looks like it can support newer libvirt, but just because a distro
updated a library doesn't mean we have to update.  IIRC, for ubuntu they
use cloud-archives to get the right version of libvirt, does something
like that exist for centos/redhat?
