Hi everyone, perhaps someone can shed some light on a floating IP issue.
I have 2 nova-compute nodes (call them alice and bob), one of them (alice) is also running nova-network. bob uses alice as its --metadata_host and --network_host. I assign a floating IP to a guest running on bob. Expectedly, that IP is bound to the NIC specified as the --public_interface on alice (my nova-network host). However, since alice has a route into the --fixed_range network over its local bridge, the incoming traffic for the floating IP is routed there, where there's no guest to answer it -- because the guest is, after all, running on bob. Now, this seems fairly logical to me in the combination of 1. a nova-network host also running nova-compute; 2. other nova-compute hosts being around; 3. those other nova-compute hosts _not_ also running nova-network (and hence there being no multi-host networking). If my reasoning is correct, is it safe to say that in order to be able to use floating IPs in an environment with multiple nova-compute hosts, you must 1. Either have a single nova-network host that is _not_ also running nova-compute (but has a network connection to the --fixed_range network, of course); 2. or run nova-network on all your nova-compute hosts, which however requires that you enable multi-host mode and also run nova-api there? Any help is much appreciated. Thanks!
