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).
