I got the metadata network accessible over a routed subnet!

The breakthrough was making sure I pointed 169.254.169.254 to the Neutron DHCP address rather than the physical or bridge IP address, this route added to the physical router (L3 switch) that serves the subnet hosting the Ironic controller.

Also, I made sure to add a host route for 169.254.169.254 to the baremetal remote subnet in Neutron so the baremetal nodes will have a proper route to the metadata subnet.

There is still some network tweaking left to do. We have a separate subnet for ESXi mgmt vmkernels since they use virtual MAC addresses and neutron doesn't recognize them. However, enabling DHCP relay for that separate subnet breaks routing which also breaks cleaning and deploying, and I need to find out where.

This is huge for our metal-as-a-service offering!

Thanks, Tom King

No, I didn't. In the beginning I wanted to say "yes" but that is for overcloud.

Now I am thinking, maybe even I do no have metadata on undercloud....

Will need to check on Monday.

Finally got it worked out except for reaching the metadata service IP (169.254.169.254) from a remote network. Did you put specific routes in place for that IP address on your physical network?

Ok

here is a small copy paste: http://paste.openstack.org/show/o4Uay0DYbAdkcfUJGOLV/

also have relaunched previous commands, as I have redeployed overcloud :)

and maybe you will be interested, in undercloud containers running:
