We're now a few weeks away from the kilo-1 milestone, so I thought it was time to update my summary of the Nova specifications that have been proposed so far. So here we go... API Add more detailed network information to the metadata server: review 85673. Add separated policy rule for each v2.1 api: review 127863. Add user limits to the limits API (as well as project limits): review 127094. Allow all printable characters in resource names: review 126696. Expose the lock status of an instance as a queryable item: review 127139 (abandoned); review 85928 (approved). Implement instance tagging: review 127281 (fast tracked, approved). Implement the v2.1 API: review 126452 (fast tracked, approved). Improve the return codes for the instance lock APIs: review 135506. Microversion support: review 127127 (approved). Move policy validation to just the API layer: review 127160. Nova Server Count API Extension: review 134279 (fast tracked). Provide a policy statement on the goals of our API policies: review 128560. Sorting enhancements: review 131868 (fast tracked, approved). Support JSON-Home for API extension discovery: review 130715. Support X509 keypairs: review 105034 (approved). API (EC2) Expand support for volume filtering in the EC2 API: review 104450. Implement tags for volumes and…

I originally read this as a series of short stories released on the kindle, but the paperback collation of those has been out for a while and deserved a read. These stories are classic Scalzi, and read well. If you like the Old Man's War universe you will like this book. The chapters of the book are free standing because of how they were originally written, and that makes the book a bit disjointed. The cliff hanger at the end is also pretty annoying given the next book hasn't been released. So, an interesting experiment that perhaps isn't perfect, but is well worth the read.

I don't read a lot of non-fiction, but I decided to finally read this book having had it sit on the shelf for a few years. I'm glad I read it, but as someone who regularly eats in the US I am not sure if I should be glad or freaked out. The book is an interesting study in how industrialization without proper quality controls can have some pretty terrible side effects. I'm glad to live in a jurisdiction where we actively test for food quality and safety. The book is a good read, and I'd recommend it to people without weak stomaches.

Here's an updated list of the specs currently proposed for Kilo. I wanted to produce this before I start travelling for the summit in the next couple of days because I think many of these will be required reading for the Nova track at the summit. API Add instance administrative lock status to the instance detail results: review 127139 (abandoned). Add more detailed network information to the metadata server: review 85673. Add separated policy rule for each v2.1 api: review 127863. Add user limits to the limits API (as well as project limits): review 127094. Allow all printable characters in resource names: review 126696. Expose the lock status of an instance as a queryable item: review 85928 (approved).

Compute Kilo specs are open

From my email last week on the topic: I am pleased to announce that the specs process for nova in kilo is now open. There are some tweaks to the previous process, so please read this entire email before uploading your spec! Blueprints approved in Juno =========================== For specs approved in Juno, there is a fast track approval process for Kilo. The steps to get your spec re-approved are: - Copy your spec from the specs/juno/approved directory to the specs/kilo/approved directory. Note that if we declared your spec to be a "partial" implementation in Juno, it might be in the implemented directory. This was rare however. - Update the spec to match the new template - Commit, with the "Previously-approved: juno" commit message tag - Upload using git review as normal Reviewers will still do a full review of the spec, we are not offering a rubber stamp of previously approved specs. However, we are requiring only one +2 to merge these previously approved specs, so the process should be a lot faster. A note for core reviewers here -- please include a short note on why you're doing a single +2 approval on the spec so future generations remember…

I know I like Scalzi stuff, but each series is so different that I like them all in different ways. I don't think he's written a murder mystery before, and this book was just as good as Old Man's War, which is a pretty high bar. This book revolves around a murder being investigated by someone who can only interact with the real world via personal androids. Its different from anything else I've seen, and a unique idea is pretty rare these days. Highly recommended.

On layers

There's been a lot of talk recently about what we should include in OpenStack and what is out of scope. This is interesting, in that many of us used to believe that we should do ''everything''. I think what's changed is that we're learning that solving all the problems in the world is hard, and that we need to re-focus on our core products. In this post I want to talk through the various "layers" proposals that have been made in the last month or so. Layers don't directly address what we should include in OpenStack or not, but they are a useful mechanism for trying to break up OpenStack into simpler to examine chunks, and I think that makes them useful in their own right. I would address what I believe the scope of the OpenStack project should be, but I feel that it makes this post so long that no one will ever actually read it. Instead, I'll cover that in a later post in this series. For now, let's explore what people are proposing as a layering model for OpenStack. What are layers? Dean Troyer did a good job of describing a layers model for the OpenStack…

Blueprints implemented in Nova during Juno

As we get closer to releasing the RC1 of Nova for Juno, I've started collecting a list of all the blueprints we implemented in Juno. This was mostly done because it helps me write the release notes, but I am posting it here because I am sure that others will find it handy too. Process Reserve 10 sql schema version numbers for back ports of Juno migrations to Icehouse. launchpad specification Ongoing behind the scenes work Object conversion Convert the compute manager to use nova objects. launchpad specification Convert EC2 API to use nova objects. launchpad specification Start converting hypervisor drivers to use objects. launchpad specification Scheduler Support sub-classing objects. launchpad specification Stop using the scheduler run_instance method. Previously the scheduler would select a host, and then boot the instance. Instead, let the scheduler select hosts, but then return those so the caller boots the instance. This will make it easier to move the scheduler to being a generic service instead of being internal to nova. launchpad specification Refactor the nova scheduler into being a library. This will make splitting the scheduler out into its own service later easier. launchpad specification Move nova to using the v2 cinder API. launchpad…

This is a just a quick list of the posts I wrote summarizing the Juno Nova mid-cycle meetup in the right order to read them, because I didn't actually have that online before. I needed to send this list to someone, so I figured its easier to just post it here.
