I am playing around for years with all major virtualization environments like all VMware products, Microsoft and several xen based solutions. But OpenVZ is the overall winner and I summarize here just a few features which make it perfect for me.
Basic features:

Anyway I installed it from the Fedora repository. I'm using Fedora 8. You cannot use Fedora 9 or even Fedora 10 that is coming out because neither one supports running as a Xen dom0.
Also, when creating a VM you need a domU kernel. Or if you use virt-manager you need an install media url. Where do you get a domU kernel? No where does it specify what is a valid install url, how you create a valid install directory from a iso file or why you can't use an iso file in the first place. I guess you are just supposed to magically know this. The docs suck ass. Why aren't there links to Ubuntu, Centos, Fedora, etc. domU kernels? or at least a hint of how you might get them?
I finally found a valid Fedora 9 install URL and got a few Fedora 9 domU's configured and setup, but what took 2 days should have taken 2 hours max.
I want to start a VPS hosting company and am evaluating Xen vs OpenVZ. I'll try out OpenVZ soon.
