Open Stack

  Hi

  I know, this does not fit in the cloud operator model nor the
openstack-neutron way of doing things. However, i have this use case:

- vmware is booting guest vm with underlying DHCP server for IPAM
integrated with DNS for host registration as the guest vms power on. So, vm
gets ip with its hostname DNS registered as it boots.

-  I started a few vms on openstack, I can attach guest vms on these
provider n/w and I can see they are reachable just like any other vm on an
enterprise network similar to vmware guest vms and this is great. However,
I cannot find any docs, option where these guest vms can cross over to
external DHCP for ip address management because the provider network
operates at Layer3.

Found this blueprint, review discussion
 https://blueprints.launchpad.net/neutron/+spec/dhcp-relay
Which is close to what i'm looking for and not updated for sometime.
Wanted to know if anyone has come across this scenario and how to get over
this.

As one of the options, validated openstack-designate service which solves
the hostname registration not the IPAM. Also it needs site DNS server
domain management .
Something, I can look at if the external DHCP server is not an option for
nova boot.

Thanks,
Swamy
