</div></div>Interesting stuff. I conceptually like the idea of nova-compute doing<br>
the leg work for sub resources (like the network) as it feels like error<br>
handling is simpler given it's closeness to the actual VMs that are<br>
running.<br>
<br>
I also like the idea of considering the RPC interface. What kind of<br>
stability / versioning exists on the Neutron RPC interface?<br>
