is this now all up for review? --johnthetubaguy 5th August 2014

No updates, all proposed code appears to have merged now, calling this implemented --johnthetubaguy 22nd August 2014

Where are the tempest tests as promised for this in the spec? I'm pretty sure that this fails if you're allowing multiple ports on the same network and you try to add a fixed_ip to an instance, the neutronv2 API code will only add the fixed_ips from the first subnet on the network to the first port attached to the instance, no other ports will be updated (or subnets for the first port):

I reported a bug here: https://bugs.launchpad.net/nova/+bug/1430512

-- mriedem 2015/03/10

Bug looks fine, added comments there on problem and options.

Tempest tests were never promised in the spec, just recommended: to quote, "Independently of this spec, tests should be added to Tempest". You are making a strong case for them...

-- ijw-ubuntu 2015-03-10

Will add the recommended tempest tests.
