Personally, I use the technique described in the Wiki  - http://wiki.centos.org/HowTos/Xen/InstallingCentOSDomU 

It has worked flawlessly for me every time. Once you have one install config file and one for running, you can easily make copies to accommodate extra guests. You don't have to do the kickstart bit if you're happy to select your options at install time, like a normal install.

When I did first use virt-manager, it seemed okay. I didn't want to become dependent on a GUI tool, though.

xen-user list is a good place for further Xen specific advice.

I would also recommend using the Xen hypervisor and tools at the gitco repository. http://www.gitco.de/repo/
