Comment 4 for bug 1152504

If I recall correctly the quotes were necessary to account for people specifying a tag that had spaces in it. From my testing, as long as you quote in both places (dnsmasq.conf file and the cli startup flags) it should work. This is what the example docs at http://docs.openstack.org/trunk/openstack-compute/admin/content/existing-ha-networking-options.html show. Are you sure you had the tag quoted in your conf file?
