[Openstack] Openstack Metadata Service

Hi,

I had tried every sollution posted on the openstack archives and it simply
wouldn't work.
Until I had the wrong idea and installed the nova-api-metadata on the
controller node and it removed the nova-api, which corrupted the openstack
deployment. So when I re-installed all the nova components (the
nova-api-metadata was removed), one reboot later and the metadata server
was running. :)))

Also, I added a route to the Private Network ( for the VM) using the router
external gateway.

The problem must have been from a bad installation of nova-api int the
controller node.

best regards,
Bruno
