With the network architecture we're moving towards, overcloud nodes will only get dhcp from Neutron for the provisioning network. The api, data, storage, etc network will support static IP configuration, or possibly, non-Neutron provided dhcp. Further, after initial provisioning, overcloud nodes will boot off the local disk instead of pxe booting via Neutron on subsequent reboots. localboot support is a relatively new feature in upstream Ironic, and we'll be enabling it soon in rdo-manager. With these changes, when the undercloud is stopped or goes down unexpectedly the overcloud would be unaffected. That being said, we still plan to have an HA undercloud at some point in the future. Also, the current virt-setup that allows testing rdo-manager via deploying the undercloud and overcloud all on vm's still relies on the undercloud vm to continue to run for connectivity to overcloud nodes. That could also be enhanced though to not require the undercloud vm to stay up. > > Thanks, > Pedro Sousa > > On Mon, Apr 20, 2015 at 6:31 PM, Mohammed Arafa < mohammed.arafa(a)gmail.com&gt; > wrote: > > > Hello all.
