Prior to CentOS 6.0 I used Xen, switched to KVM with 6.0 because it was what was supported. I thought I'd take a performance hit but for my applications (web, mail, ftp, dns, shell servers), I didn't see any noticable difference other than KVM was a lot easier.
But the fact that people are still working on getting Xen running in CentOS 6.4 tells me there must be something it does better.
One area I really would like to see working is the qemu emulation of other architectures so I could run some legacy apps on modern maintainable hardware.

What are the advantages / disadvantes of Xen / KVM?
Can't say which is better, but KVM works very nicely. I use it to run several Linux and Windows virtual machines that act as servers, but which are not graphic intensive. (just basic desktop use)
