Hi all,
I'd be interested in attending the next Dojo in Brussels.
I actually wanted to propose a talk for it, titled "Tuning the Xen Hypervisor for Optimal Performance". Something similar to this has been delivered already at previous Dojos, but there is always something new to say about such a topic. :-)
Here's a few more info:
As we all know, the Xen hypervisor powers some of the largest and most popular public cloud services. Hence, the session could be useful to people wanting to tune and optimise their instances and the workload they're sending to the Cloud.
In fact, Xen has several options and different kinds of guests. The talk would describe the various types of guests supported by Xen, give insights about their respective strengths and weaknesses and advise under what circumstances, and with what parameters, one should use each one of them, in order to achieve the best possible performance.
Of course, some of what is happening with the CentOS Virt SIG would be mentioned, and I'd be available to try providing insights and answering questions about it, although I'm not directly involved in it.
About me, I'm a Citrix employee, paid to work 100% on my time on Xen as an Open Source project. I'm in the same team as Roger, the guy that gave a talk similar to this at previous Dojos.
Thanks and Regards, Dario
PS. Sorry if I'm sending this as a new message, and not as a reply to the CfP, but I just subscribed to centos-promo! :-)

BTW, if some more practical and 'hands-on' style content is more welcome, I can include a few suggestions, and maybe even a small demo, about how to use tracing in Xen, with particular focus on figuring out what particular vCPUs are running on the host's pCPUs at any given time.
Thanks and Regards, Dario
