Also, because this issue involves packages, it isn't a neutron bug.
Moving to openstack-manuals as we can at least provide a workaround for
it.

Title:
Obscure error message if missing 'ipset' utility
Status in openstack-manuals:
In Progress
Bug description:
In Liberty (7.0.0) and possibly prior releases, if you enable 'ipset'
via the 'enable_ipset' option in the [securitygroup] section, a node
running the Linux bridge agent that lacks the 'ipset' utility (e.g.,
due to a dependency issue) produces a rather obscure error message
when attempting to launch an instance. Consider making this error
message more useful.
