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

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.

You are asserting the Xensource lacks what the CentOS supplied xen has? wow
I should also state that Xen is the coolest thing I have played with in ages. I don't want to suggest I am not fond of it in any way, I love it and use it. I just don't think the commercial product is polished enough. I really feel some trivial lustre could be massaged into it. If I was shelling out cash, and the choice was vmware or xensource you cant compare. Vmware has been at it a long time and thier product is just so polished and solid.
YMMV, jlc _______________________________________________ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt
