openstack metadata centos vm vs ubuntu vm -- Grizzly

Hi All,

I got an interesting issue.

If I instantiate an Ubuntu vm the metadata route does not exist. However, when I use the same openstack server to launch a Centos 6.04 vm the route is present. The result of this is that the metadata server route to host is not present at boot time. What's different between how centos learns the route and how ubuntu learns(disregards) the route. Something in DHCP is being ignored on ubuntu. Any help is appreciated.
