I can't reproduce here.
Are you using the EPEL OpenStack packages?
On 6.3 based systems please ensure you install the dnsmasq-utils,
which installs utils that may be related to this.

If using the EPEL packages, I'd advise logging this
at http://bugzilla.redhat.com/ against the EPEL version
of openstack-nova, so that we don't miss anything.

Pádraig.
