Currently the LVM2 package is installed by the
openstack_hosts role for the integrated build,
and by a test playbook for the role tests.
This does not seem sensible to me - it would
be better to ensure that the role installs the
distro packages it need in order to function
properly.
Additionally, it is not possible to setup a
loopback device inside an LXC container after
some recent updates to LXC. The secondary
cinder-volume service for LVM2 therefore
does not work, so it is removed from the
inventory to buy some time to come up with
an alternative solution.
