In newton we are setting both nova::host and neutron::host values explicitly to the fqdn. This can cause problem during upgrade from Mitaka. The previous host value (defaulting to python socket.gethostname) could return only the hostname[0]. It means that during upgrade we are changing this identifier. At restart nova/neutron creates *new* agents. Those agents are then unaware of existing workload. For neutron, the problem is that due to [1] and the fact the L3 agents are in HA mode, the previous defined workloads on those agent get lost and FIPs become unreachable. For nova it's no longer possible to send commands to (before upgrade) existing vm anymore. This patch checks the current live value of the host parameter through a fact and set the nova::host and neutron::host value to it if we are not in a deployment (upgrade/update) For nova, we directly use nova-manage to get the current live value. Using the mysql parameter directly has the advantage that it's defined on all types of node (controller *and* compute). As a matter of fact the required auth parameters are usually not defined on compute node. For neutron, when auth is available in the configuration (on Controller) we use that. There is no neutron-manage equivalent here so we use the nova value when auth is unavailable. When host is unset they both use python.gethostname, so it should be the same value. Using auth on controller add another level of confidence though. And the controller are where the l3 agents are, so better be safe than sorry. This patch is newton only as it's where we are setting for the first time this parameter. After that (ocata on) we use[2] to make sure that those parameters are never rewritten.
