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