Notable Discussions

Nova / Trusted Computing Pools related security notice (OSSN 0059)

Summary from the original security notice: “A trusted VM that has been launched earlier on a trusted host can still be powered on from the same host even after the trusted host is compromised.  More in the original post or the OSSN itself.

A reminder to projects about new “assert” tags

Over the last few months the TC defined a number of “assert” tags – a standardised way for projects to make certain assertions about their projects.  In his email Thierry Carrez reminds all concerned (basically PTLs and Project Cores) that the time is upon them to see if these tags should apply and if so to start using them.

In time this information will be added to that already displayed in the OpenStack Foundation’s Project Navigator hence the desire to get projects using these tags as soon as possible.  For operators and other non-developers, the use of these tags and endeavours like the Project Navigator promise to make the process of evaluating an OpenStack projects maturity a little simpler.

Vitrage – a Root Cause Analysis engine for OpenStack

Announced at the Mitaka Summit, a post to the list provided some more information on the Vitrage project – part of the broader Telemetry umbrella project for OpenStack,  The Vitrage developers would “like it to be the Openstack RCA (Root Cause Analysis) Engine for organizing, analyzing and expanding OpenStack alarms & events, yielding insights regarding the root cause of problems and deducing the existence of problems before they are directly detected.”

Noble goals and early days but a worthwhile and much needed set of functionality

What should the openstack-announce mailing list be ?

Tom Fifield kicked off a thread discussing what the best use of the mailing list is from herein.  Originally conceived as a low traffic read-only list he makes the point that with the addition of more (arguably) developer oriented content it’s become rather high traffic.  The concern being this appears to have put some folk off with them either filtering the list or unsubscribing – and so possibly missing the urgent content such as security notifications.

While there has been a little discussion since his first post on Friday input from a broad range of readers would be welcome.

Is booting a Linux VM important for certified OpenStack interoperability ?

On behalf of the DefCore Committee Egle Sigler asks for feedback on whether the ability to boot a Linux VM should be required for certified OpenStack interoperability.  A quick glance at the comments in the review cited suggests this is anything but a simple topic particularly once you consider containers and bare metal clouds in an environment…

Autoscaling both clusters and containers

Ryan Rossiter kicked off an interesting thread about autoscaling both containers and clusters. Essentially have the ability for a cluster to expand when the concentration of containers gets too high. Evidently there was some discussion about this in Tokyo with at least one demo being given using Senlin interfacing to Magnum to autoscale.

Developer Mailing List Digest

Originally a section within the OpenStack Community Newsletter, Mike Perez’ excellent openstack-dev digest is now available as a digest sent to the openstack-dev mailing list as well as being posted on the OpenStack Foundation’s blog.  I commend it to you if you’re after a deeper and/or more technical analysis than Lwood or other sources provide.  Here are the links to the Digest for November 7-13 and 14-20.

Discounted documentation changes

While the sprint in question is alas over at the time of writing, this post from Joshua Harlow about the Oslo projects virtual documentation sprint is too well written not to note :)

Midcycle dates and locations

A few more midcycle discussions this past week

  • [ironic] The Midcycle discussions from last week kicked off by Lucas Alvares seem to have settled on the idea of a virtual midcycle as proposed by Jim Rollenhagen
  • [manila] A survey for midcycle attendees/interested persons – Ben Swartzlander
  • [cinder] Mitaka Midcycle Sprint is on 26-29 January in North Carolina, USA – Sean McGinnis

Post Mitaka Summit Summaries and Priorities

A few more Summaries and Priority lists rolled in from the Mitaka Summit
