My experience has primarly been with Xen. I have helped a company successfully deploy Xen on CentOS. They had a really nice cobbler setup and were able to leverage it nicely to make the transition to virtuals easy. They found our running xen book (http://runningxen.com) a great resource. Another factor to consider is the application workload and the guest requirements. Over the last several years, we at Clarkson, have done a lot of performance studies on virtualization systems (as well as writing the book on Xen). You can find links to much of this work at: http://people.clarkson.edu/~jnm/publications/publications.html http://todddeshane.net/research.html http://xen.cosi.clarkson.edu/ Hope that helps, Cheers, Todd On Thu, Sep 11, 2008 at 4:25 AM, admin <mick at mjhall.org> wrote: > Some factors swaying my boss towards Xen/XenSource: > > On the quotes we've been getting, XenSource would cost half of what VMWare > ESX would cost (not the stripped down free download obviously). > We are a cash-strapped organisation, so the difference is significant. > > We are also looking to move as much of our server infrastructure as possible > to a standardised RHEL/CentOS platform, whether as hosts or as guests. > VMware runs on RHEL/CentOS of course, but a > supported-out-of-the-box-by-the-OS-vendor alternative (like Xen) always has > appeal. > > My boss is also interested in Citrix for some other stuff they do (virtual > clients/application delivery). > > For my part, looks like I'm going to learn Xen, then learn KVM. > > I am just starting with Xen ... my sandbox is a new Dell PowerEdge 840 with > Xeon Quad Core, 4GB RAM and 4 x 750GB HDD on a hardware RAID 5, so far it is > all running like a dream. > > Joseph L.
