After I wrote my degree dissertation about Xen, I took a Citrix Xenserver 4.1 training and I successfully passed the Xenserver certification.

Even if I disagree on the evolution of the project (Red Hat resigned from it, Linux distributions are optionally supported if you install the Linux pack from another DVD and, as we expected from Citrix, virtual servers running Windows are the priority of this platform), I already have a good knowledge of this technology and since it will be soon part of HP’s Insight dynamics, a management software managing virtual machines, I thought it was a good opportunity to go on with Xen. Moreover, it is still an open-source project and that is the reason why a VMware training would not have interested me that much.

Finally, I hope that HP will continue to support other virualization projects such as KVM, which is already part of the Linux kernel, and is really being pushed forward by IBM and Red Hat, for example.
