Oleg - this is great! I tried to find you on IRC to recommend we put this on a etherpad so several of us can collaborate together on requirements and brainstorming. On Nov 18, 2013, at 10:54 AM, Oleg Gelbukh wrote: > Hi, > > I summarized a list of requirements to the config validation fram

Re: [openstack-dev] [Nova] Configuration validation

Hi, I summarized a list of requirements to the config validation framework from this thread and other sources, including IRC discussions so far: https://gist.github.com/ogelbukh/7533029 Seems like we have 2 work items here, one being extension which adds more complex flags types to Oslo.config,

Re: [openstack-dev] [Ironic][Ceilometer] get IPMI data for ceilometer

Hello. I have a couple of additional questions. 1. What about IPMI data that we want to get by polling. E.g. temperatures, etc. Will the Ironic be polling these kind of data and send them directly to collector(or agent)? Not sure if this belongs to Ironic. It would have to support some

Re: [openstack-dev] [Oslo] Layering olso.messaging usage of config

I see it as important (and not theoretical). I'd like to use oslo.messaging (and oslo.messaging.rpc) in taskflow (to prototype how a distributed engine would work using it) and bringing in a library which requires global configuration is almost a non-starter for me. Although taskflow is targeted a

Greetings all stackers, I propose that we add Anastasia Karpinska to the taskflow-core team [1]. Anastasia has been actively contributing to taskflow for a while now, both in code and reviews. She provides high quality reviews and is doing an awesome job with the various taskflow concepts (and is

Honestly, with that reasoning, this approach strikes me as a technical solution to a political problem, a band-aid on a sprained ankle, and so on and so forth in that pattern. There was no shortage of talk about cross-project coordination challenges in HK and Portland, so it shouldn't be news t

No, it does not have any parking. I suggest coming in on BART and exit at the Montgomery station and coming south on 2nd to Folsom by foot. The Courtyard hotel across the street has parking but that is very expensive and may be full. Parking at the meters on the street is not a great option eit
