I have had most of my test environment, aka puppetmasters, test mysql setups etc running in KVM for the past couple of years .. (yes I`m still using a lot of Xen in production environments, but we’ve also been using KVM for a while already .. it’s a good mix) , Virtual box has always been the lesser loved Virtualization platform , however while playing more and more with Vagrant Up I realized I needed to convirt some boxen (e.g my PuppetMaster) to Virtualbox, and google was really no good help(most people seem to go the other way , or want to use some proprietary tools )
Has anyone noticed that pretty much every puppet module one finds on the internet by default enables the service they try to configure in the module
When looking at it from a single machine point of view it makes sense to include the module , have it configure your service and directly enable it by default.
So I started wondering .. isn’t there anybody out there who is building clusters ? Where services have to configured on multiple nodes but should NOT be running acitvely on all nodes by default because there is an external tool which manages that for you (Pacemaker framework eg.)

Next weekend saturday I`ll be giving a talk about devops at StartUp Weekend Brussels, from what I’ve read so far it promises to be an audience that needs the talk,
The week after I`ll be speaking at the DrupalDevDays, again about devops , however this time with a touch of Drupal , giving a devops talk at Devoxx last year to a Java audience learned me that the devops evangelist need to go outside of their usual conference audiences and als talk to the people that are usually in the other silos.
Just last last year we’ll have a Devops meetup just before Fosdem,
I’ve setup a page for registrations , that way we’ll know how many people to make reservations for.
If possible we’ll go to the same place as last year .. walking distance from the Fosdem Beer event.
That’s the question Xavier asks in his blog entry titled
Security: DIY or Plug’n’Play
To me the answer is simple, most of the appliances I ran into so far have no way of configuring them apart from the ugly webgui they ship with their device. That means that I can’t integrate them with the configuration management framework I have in place for the rest of the infrastructure. There is no way to automatically modify e.g firewall rules together with the relocation of a service which does happen automatically, and there is always some kind of manual interaction required. Applicances tend to sit on a island, either stay un managed ( be honest when’s the last time you upgraded the firmware of that terminal server ? ) , or take a lot of additional efort to manage manually. They require yet another set of tools than the set you are already using to manage your network.
They don’t integrate with your backup strategy, and don’t tell me they all come with perfect MIB’s.
A couple of weeks ago I ranted about being able to crash about any available music player on Fedora, and the gazillion bugs I filed for that ..
At last the the problem is solved, as mentioned in https://bugzilla.redhat.com/show_bug.cgi?id=657971#c17
this is most probably a bug in ffmpeg which is provided by rpmfusion. and which is solved by installing gstreamer-plugins-ugly
When I first started out giving talks about devops , I realized that I was preaching to the choir, some Barcamps, the Keynote at Loadays , the Dutch Unix Usergroup etc .. lots of people in the audiences knew about the pains we were trying to solve, lots of them already knew some of the tools we use and lots of them already talk a lot with their developers or are part of the deveoplment teams
