"Progress" field from Nova API for servers never updated

[Daryl Walleck]

While a server builds, there is a "progress" field returned by the Nova API for a server that represents where a server is in the build process. When using the Ironic Nova driver, the field never appears to always be 0, even when the server has finished provisioning.

Is this an ironic bug, or a nova (ironic driver) bug? Is 'progress' a % of amount of time it will take to complete?

Did you just want it to show 100% when it is done?

[Julia Kreger (juliaashleykreger)]

I would classify it as a defect, not necessarily a bug in our ironic virt driver that lives in nova. Realistically, I'm not sure there is anything we can do to support this since we don't get any sort of atomic status updates on the process of the write-out of the image from IPA, and suggest that we decide not to fix this.

[Ruby Loo (rloo)]

Discussed with Julia on irc [1] and there is merit (assuming this means that ironic needs to have the progress info, to feed into the ironic-virt-driver-in-nova) although we don't see how it can be done in the near or later future of ironic. It seems like this would be an RFE in ironic and maybe a bug in nova. Going to mark it as wontfix. It can be revisited later.
