Today I plan to spend some time with virtualization. I have a video to watch from XENsource and a live Knoppix based CD for OpenVZ I got at SCALE6x.
If I have more time I might do some playing with EC2.

Ralf,
Don't waste your time with Xen. OpenVZ is much better. A bit harder to provision then Xen. But you can use koan/cobbler (see http://et.redhat.com/page/Main_Page) to speed up OpenVZ provisioning. I deployed a Xen guest on Ubuntu on Sunday. I twittered about it. See https://help.ubuntu.com/community/Xen for instructions.
Xen is certainly less overhead then VmWare. But more than OpenVZ. The product that Mike and I are building is based completely on OpenVZ and Centos5.1.
Hope this helps
OpenVZ performs a lot better than Xen.
There are two advantages Xen has over OpenVZ:
1 - You can run a different kernel within a Xen VE (and load kernel modules)
2 - Xen VE's can make their own swapfiles.
The downside of course, is that Xen is noticeably slower than VZ, and is a LOT more annoying to work with. OpenVZ is much easier to administer and troubleshoot.
