RHEV 3 beta

Red Hat has released the first public beta for RHEV 3 in the last week or so. I didn’t have time to play with it since yesterday, waiting for the rest of Irene to strike my city.

So, I grabbed the documentation, go through it rapidly and start the installation on a spare server I have at home. The first thing to notice is how wonderful it is to just “yum install rhevm”! Seriously, compare that to the need to install Windows 2k8, Active Directory, .Net, etc, etc… This is a major step up for RHEV.

After playing with RHEV for the whole day, here is what I conclude :

– For a first public beta, RHEV 3 is extremely stable. I saw some problems here and there but nothing major. There is some errors in the documentation and some problems accessing the Spice console with Fedora 15 and Gnome 3 (and this one is not necessarily a RHEV problem). Everything is stable, smooth and work as advertised. I am impressed because I thought that porting from .Net to Java would cause more problems than that.

– RHEV 3 also gave me the chance to play with FreeIPA, which is in “Technology Preview” in RHEL 6.1. Again, really impressed with this product and will be sure to look at it again on it’s own in the near future.

– The upgrade to RHEL 6.x really show : the performance are amazing. I look forward to try RHEV 3 on bigger hardware than what I have currently. This is largely due in performance improvement in the kernel and KVM : KVM performance improvements and optimizations

– I like how Red Hat used their technologies combined with other major Open Source products : JBOSS, OpenJDK, PostgreSQL, KVM, RHEL 6.x, FreeIPA, etc. I like that a big project like RHEV based on Windows, .Net, Active Directory and SQL Server can be ported to stable and trusted Open Source equivalent.

The only downside from all this is that you still need Internet Explorer to access the Administration console. After searching for a bit, this is supposedly going to be fixed in RHEV 3.1. This is a small downside for all the gain that RHEV 3 come with.

Gnome 3

No, this is not another post to describe my feelings about Gnome 3, what we should have done or should we have shipped Gnome 2 instead😉

This post is more of an open question to the community for some information that I cannot find. I almost finished the configuration of my setup in Gnome 3 but I have some interrogation :

1 – I tried to remove the keyboard applet in the system tray with the same logic that the nobluetooth and noa11y extension. This effectively work but leave me with the default Gnome 2 keyboard applet. And I cannot seems to find a way to remove that one.

2 – I cannot find where the configuration for the launcher in the favourite bar are stored. I know that we can edit the menus with “alacarte” but I want to see where Gnome 3 store that an application should appear in the favourite bar.

3 – I search the documentation to see how Gnome 3 track the applications windows to highlight running applications in the favourite bar and found nothing. I know it’s not based on the window title with my experiment but I found no other way.

Also, if anyone want to hide the battery icon apart from when it’s charging/discharging (like in Gnome 2), you can run this command as your user :

GSETTINGS_BACKEND=dconf gsettings set org.gnome.power-manager icon-policy charge

Apart from that, I find that Gnome 3 is really powerful with an easy extension system, just look at the number of extensions that got out since Gnome 3 was launched. I look forward to what can be done!

Finally got my RHCA!

Wow, I finally got the result of my RH442 exam and I pass! This was my fifth certificates of expertise, so I got another mail from Red Hat confirming that I got my RHCA!

My goal was to get my RHCA in one year, passing all the exams on the first try. I took 4 months more but I got my objective of passing all of them on the first try!

This is not really related to Fedora but I just wanted to share that😉

SystemTap client/server tutorial

I just wrote a small tutorial about the client/server mode of SystemTap. It helps using SystemTap in production environment by using a dedicated server to compile all your SystemTap scripts.

The tutorial is not 100% completed, I will add the items in the TODO section as soon as I have some time to do so. If you spot any error or have any feedback, please feel free to comment here!

Fudcon is over…

This is now the time to pack our stuff and go back. My flight was cancelled because I was connecting in Chicago but I was lucky enough to call Air Canada and got a flight the same day, connecting in Toronto!

My luggages are completely full : 50lbs for my check-in and 20lbs for my carry-on! A big thank you to everyone that made it possible for me to bring back swags, media and the two beautiful vertical banners back for the Canadian Event Box. I will post pictures of them soon.

I had a very good time in the past 4 days at Fudcon. Meeting so many great people and talking about what passionate us is a dream come true. It will be hard to go back on talking on IRC and mailing list but at the same time, I think it will make the understanding easier. I was at the dinner with Jared (yes, it was me the French-Canadian ;)) and what he said is true, the need of meeting face-to-face is really important.

Seeing such a huge amount of passionate people gave me a big motivation push to continue my work on the Ambassadors and Packaging teams. What I hope is to distribute this motivation back during the following year to encourage more people to start contributing to the Fedora Project.

So, thanks to the Fedora Project for giving me the opportunity to meet a part of the community and the chance to make my own contribution! See you at the next Fudcon!

Fudcon, day 2

Second day of Fudcon is now over. It was a really productive day for me, having get many media from Clint, some more swags from Ben and two Fedora vertical banners from Ben and Larry! I hope everything will fit my luggage so I can bring all this in Canada with me!

The conferences in the morning were really nice, especially the introduction on Inkscape made by Mairin Duffy. She was right, after the conference, I at least understand enough about Inkscape to be able to do some basic mockup in it!

In the afternoon, Fudcon got a new feature : lightning talks! It was really nice to see people talk about something they love in 5 minutes.

After that, it was the hackfest time. I take the opportunity to go outside to work on my projects, so I can take at least a little bit of sun before returning to Quebec!

In the evening, the hack room was full with many things going on : talk, hacking, board games, poker, etc. It was a really good time, but maybe I should have got to bed earlier😉

Now looking forward to the full hackfest day tomorrow!

Fudcon Tempe, day 1

The first day of Fudcon is over. Many great conferences and many good discussions on all things related to Fedora.

This day let me meet many people that I work with on IRC or mailing list, so, that was nice to finally meet face to face and have a good talk. Also, I had the chance to speak French a little bit, having met with Xavier from the Fedora France team and also with David from Montreal.

The Fudpub event was really nice. Having the chance to talk about Fedora in front of a good beer with many great people is really nice. Also, this is a great occasion to have more personal talk with people than we have on IRC for example.

I look forward on day 2 of Fudcon!
