<para>The GroupAffinityFilter ensures that an instance is
scheduled on to a host from a set of group hosts.
To take advantage of this filter, the requester must pass a
scheduler hint, using <literal>group_hosts</literal> as the
key and a list of instance uuids as the value. Using
scheduler hint, using <literal>group</literal> as the
key and an arbitrary name as the value. Using
the <command>nova</command> command-line tool, use the
