Public bug reported:

When metadata networking is enabled, neutron will generate a dnsmasq
configuration that includes classless routes.

The RFC states that those routes should include the default route if
they are defined, and that the DHCP client should ignore the default
router.

This causes standards-abiding DHCP clients like dhcpcd to not provide a
default gateway when running on nova.

At https://github.com/openstack/neutron/pull/22 you can see an example
of how to fix this.
