A great KernelRecipes 2015 last week


KernelRecipes is not like other Open Source Events.

First it’s friendly. I’ve been invited to talk about the interactions between a hardware manufacturer such as HP and the Linux community. And honestly, not being a kernel developer, I think I was more invited because of my firendly relationships with the organizers of the event, rather than for my relevance to the event. Hopefully, I’ve been able to bring some appropriate info anyway.

Then it’s remaining a small event, gathering around 100 people, all very committed to Linux kerel development. Small but highly focussed. To be honest, again as I’m not a kernel developer, I had a hard time following most of the conferences once they started digging into some aspects of the kernel.

And it’s great because of the high quality of the speakers present on stage (myself excluded). Look at the schedule, and realize that it was near a Kernel Summit as it can be without being one ! And I only attended day 2 and 3.

We had first David Woodhouse from Intel on Device Tree and ACPI. Typical session where I understand only parts of the talk, not being involved in embedded world. For the dummies on this topic like me, I’d recommend Thomas Petazzoni’s presentation as a starting point.


He was followed by the star of the event Greg Kroah Hartman, fellow at the Linux Foundation and who is after Linus the one devoting the most to the kernel especially on stable branches. And as for every great speaker, you can give them whatever topic to cover, they make it interesting. Even more when they have chosen it, and didn’t make that talk since a couple of years. It was brilliant. With live publication of two RCs and an official stable kernel release named … “Kernel Recipes” of course :-) That talk was really inspiring and lively as you can see:


And Greg was talking, as well as all other speakers in a very nice room (Lended by the Mozilla Foundation) completely full ! And I think most people were like me impressed by the level of git+mutt mastery Greg showed, as well as the automation he developed to help him. I couldn’t have thought it was so “easy” to publish 3 different branches of the kernel while explaining everything in parallel in a 50 minutes talk !!!


William Dauchy from the french registrar Gandi was then on stage to explain their network usage (large layer 2 LAN spread across DCs with TRILL).


In the afternoon, we had a talk from Eric Leblond on packet filtering and the Suricata IDS. Pretty clear again and a deep knowledge on this topic.


And then François Romieu explained his practice around Ethernet drivers development. I must confess I had difficulties following that talk, which I fuond less well architectured with probably too much digressions, while being very comitted.


An auction was then organized in order to support La Quadrature du Net in their activities. It was an excellent idea IMO, and was lead y Erwan Velu who suceeded to generate great interest from the audience. I didn’t won an auction, but I’m anyway a sponsor of La Quadrature.


I had time to pass the evening with my older daughter (and we enjoyed a great concert at the Philharmonie de Paris with a fabulous Stabat Mater of Rossini, the choirs lead by Lionel Sow in particular)


The 2nd of October, the organizers had as many key kernel contributors as I described for the second day !
We started with Jan Kara to explain IOs, followed by another kernel major actor, Jens Axboe, working now for FaceBook and who was extremely didactic in his way to explain storage scalability aspects. Again an excellent talk to recommend.


Mike Turquette was then on stage for explaining driver framework followed by an active contributor to the event by his questions and feedback, Willy Tarreau, who again made an excellent presentation on stable kernels, maintenance of these and which one to choose to build products, such as what he does in his company around HA Proxy.


I had to leave before the end of that day, but I was impressed by the quality of the event, the level of the speakers, the ability to gather so many big names in the same place, and also the active participation of the audience, and the fact that speakers stay in the room to listen to other talks and contribute back. That’s how events are the most efficient IMO.


So very honored to have been invited, many thanks to the organizers (especially Anne and Erwan) and I hope next time HP will accept to sponsor this very valuable event for the Linux kernel community.

OpenStack meetup and Kernel receipes next week


While I’m involved this week in the delivery of an OpenStack fast track training, we’ll have our 7th Rhône-Alpes-Auvergne OpenStack Meetup next Tuesday in Lyon where we’ll talk about deployment method for OpenStack, covering ansible on the HP side. I’ll then be in Paris for the 2015 edition of Kernel Recipes talking about Hardware Manufacturer and Linux kernel relationships, based on my HP background.

As usual if you want to meet and talk about anything related to Open Source or Early Music, feel free !

Everything you want to learn about UEFI will be discussed at LinuxCon EMEA


During the upcoming LinuxCon Event HP’s VP and Fellow Dong Wei, Chief Executive of the UEFI Forum will host a UEFI mini-Summit the 7th of October (in Dublin) from 9:00AM to 6:00PM. This is free to attend and will cover “how to” guidance, implementation options, and firmware tools and resources available for successful ARM and x86 platform integration using the UEFI ecosystem. Details are available at

Feel free to come for this technical deep dive with experts from HP, Insyde, Intel which will help with your transformation to adopt that key HP ProLiant Gen9 technology.

Contact myself if you want to organize specific additional sessions (especially with HP customers) around UEFI or Redfish with Dong Wei. And feel free to drop me a mail if you’re around and want to talk of these topics, Linux on ProLiant, MondoRescue, or whatever you would find interesting to discuss with me while I’m attending the event.

I hope to meet you there.

Mondoescue 3.2.1 is now available … with effort and pain !


Believe it or not, it has been one of the most challenging version to produce ! And one which was really awaited by lots of people.

First all those of you who had problems restoring big files with 3.2.0 which had issues with that. Now that’s solved (was already with the beta previously).

Then those of you who had a RHEL 5 system. 3.2.0 wasn’t working, and 3.2.1 should be much better. Similarly for the people using RHEL 7. This is the real first version working for RHEL 7 available of MondoRescue. I’ve made most of my tests with a RHEL 7 VM in order to track all the errors which were remaining for that env (also some smaller but annoying ones). The root cause is that I had a customer wanting to move to that version for RHEL 7, and I wanted them to be happy with the result. Doesn’t mean they won’t encounter issues, despite what I did, but I’m much more comfortable to handle the cases in their support contract (Yes this is a paying customer).

And finally those of you who were trying to have a working environment for a UEFI based machine with RHEL 6. UEFI wasn’t working at all with 3.2.0 (and previous versions) even if EFI was working on Itanium systems. So this time I used a real system to make again lots of different tests, and solving again lots of issues linked to the support of UEFI, and now I’m happy with the result. The media made is recognized by the UEFI shell or the HP ProLiant guided boot menu. And a full backup / restore works also on it. So that other customer (an HP one, but not a paying one from a MondoRescue perspective… yet) should as well be happy and be able to use MondoRescue to perform its clones and installs correctly.

Could it be better ? Of course. RHEL 7 + UEFI are not yet friends. That will be for 3.2.2, as I want to keep my job ;-). Few bugs in trac have been addressed during these last 8 months, sorry for that. But a lot not mentioned there have been solved, and that was most of the work. And a lot of work has been put (commit hours are real !) into solving the customers needs and deliver that version on time. That’s probably why I hate time based releases, as it forces you to deliver (which is always good), but not with the serenity which should be part of an OpenSource development. Of course, that’s my fault ! I should have anticipated these requests (UEFI and RHEL 7 are there since a long time). But hey, this is still not my day job at HP. So I can only do my best as time permits. And I have a lot of other hobbies that I’ll be back to now so they can also know some progress. That’s also why I do not make more regular releases. But patches are always welcome.

Anyway, pain is over, a new version is here. Test it, report feedback, try to not break it too much, and remember to do regular backups whatever the tools you use.

Redfish 1.0 is now out and soon used by our projects


Recently the DMTF announced that the Redfish standard had reached version 1.0, the first usable for production.

If you don’t know Redfish yet, and don’t want to read the full spec, I can summarize it very roughly as a cross-manufacturer RESTful API to configure Hardware systems and recover info from them. Pretty cool in fact as this was a missing brick for a full Open Source based multi-platform Software Defined Infrasctrucute.

Now remains for us to update our python-redfish with it, and start supporting more features now it’s stable. That the first step will allow Ironic, the bare metal component of OpenStack, to have Redfish support, which is IMHO a very highly desirable feature. Not for Liberty, hopefully the spec will be ready for M and code sufficiently developed to allow us to win a slot in the Summit !

Then it will also allow us to advance on the other project we’d like to promote: Alexandria, which is a clever (of course, I’m part of the design team ;-)) way to interface CMDBs (well the one who are themselves clever enough to have a parametrized data model such as iTop) and Hardware information providers such as Redfish.

Imagine that you rack a new Refish compliant server (HP ProLiant Gen9 are among the first to provide already a subset of it), cable power and management board, integrate some info on that machine in your CMDB (iLO credntial and IP address e.g.), and ask through Alexandria that the rest is filled by Redfish calls. And kept updated as time passes. Well, that’s exactly what we try to achieve, as this is one of the need we have to maintain our Solution Center CMDB up to date as easily as possible.

Lots of good ideas, but not enough code to show for now. Hopefully, we should be able to have an Alexandria demo with somple drivers ready for the upcoming OpenStack Summit… and be able to travel to exchange our views with other OpenStacker around all this.

Some personal news around OpenStack


I’m trying to be more and more involved around OpenStack, as much as my time allows me of course.

So some recent news about that:

1/ I’m now a member of the Franch OpenStack Association Board and really proud to be listed alongside real long time contributors and advocates of the project.

2/ I’ve become an ATC during the Liberty cycle due to a modest contribution on Ironic. But it gives me the possibility to attend the Tokyo Summit !

3/ I’ve contributed to 3 proposals of talks for the upcoming Tokyo OpenStack Summit: the first one on the work we do to add support for Redfish in Ironic. The second is on a new project called Alexandria which we would like to see becoming an OpenStack project in the future and which is a CMDBaaS solution. Early stage but pretty neat ! And finally, we want to expose our view around a Software Defined Infrastructure with OpenStack.

If you think that any of these 3 presentations is worth listening during the upcoming Tokyo Summit, then vote for us before the 30th of July !!

I’d like to share other thoughts on the big tent and the community, but that will be for a next article.

For those of you wondering why and MondoRescue versions are not published more regularly, that gives you a hint ;-) Even if I made some progresses recently I also need to document !

See you there to talk of these subjects or something else as you see fit. I’m around the whole week.

Représentation HP à une table ronde du congrès Curie


J’ai été invité à parler à la table ronde du congrès CURIE modérée par Eric Horlait

Son thème est: “CLA, un mode de coopération original pour animer une communauté du logiciel propriétaire” (sic). J’y aborderai pour ma part la manière dont HP gère son engagement auprès de communautés du logiciel libre et le gestion des contributions.

Je ne suis pas encore bien sûr de comment cela va s’articuler, mais si vous êtes curieux comme moi, rendez-vous demain à Pau pour le savoir !

Software Defined Compute: Redfish and Ironic at the next OpenStack Summit


The future is already here !

In fact here ! This is a new specification which is gaining traction to allow hardware configuration of systems through a RESTful interface. All new HP ProLiant Gen9 servers from HP are providing a first version of what is not yet the standard, but looks very near to it, and provide already a rich interface.

This is pretty exciting, as it will allow people like me working on Disaster Recovery e.g., or people like Devananda van der Veen who is the Ironic PTL (OpenSTack bare metal deployment component) or many others to have, when it’s ready, a single interface to configure the servers from different manufacturers following the Redfish Specification (as of now HP, Dell, Emerson, Intel). And it’s much more feature rich than IPMI, so you would be able to go well farer with it and reach a real Software Defined Compute node.

In order to make it usable for Ironic we’ve started to work on a low level python library (python-redfish) on which we’ll be able to build the Ironic driver for Redfish later on. This is work for Liberty and after of course. And as Ironic can be also use alone, I’m more and more thinking of using it as a way to provide MondoRescue images for bare metal deployment as an additional feature over media boot. Especially if there are plans to have a standalone web interface for Ironic !

If you want to learn more on the HP implementation of the RESTful API, there is a webinar organized Wednesday, April 29, 2015 from 10:00 am CDT to 11:00 am CDT. Register from

And if you want to learn a bit more of where we are on this, read the code (easy for now) or come at Vancouver for the upcoming OpenStack Summit to discover it.

Attending HP Helion MVP next week in Sunnyvale


I’ve been recently awarded as an HP Helion MVP. And immediately after, invited to participate to the first HP Helion MVP Event in Sunnyvale on March 18th thru 20th, 2015. Looking at the mmebers and the presenters, that will be a great event, and I’m sure I’ll learn a lot through the discussions and presentations we’ll have.

On my way to the US, I’ll go through Seattle to meet with some HP colleagues arriving Monday night, and departing to Sunnyvale on Tuesday evening.

All that is a short trip, just before our big HP internal EMEA Event the week after, but I’m sure it will be worth the effort. And if you’re around as well, and want to talk about Open Source @HP, disaster recovery or cloning with MondoRescue, continuous packaging with or Helion OpenStack of course, feel free to drop me a mail so we can meet and talk.
