[CentOS] xen on CentOS 4.7

Hi - has anyone gotten Xen on CentOS 4.7 to run successfully
using Windows XP as  the guest OS?

I tried VirtualBox but it doesn't appear to work (at least for
Windows XP) for a CentOS 4.7 on a Dell Precision WorkStation
390 (quad.)

In fact, it pretty easy to crash the machine using the
command line interface.

There's blurb on the wiki

    Move a native CentOS4 installation into a Xen DomU

but that appears to be Xen running on CentOS 5 install of
Xen.

I've installed the package kernel-xen.

I'm new to Xen and I'm not familiar with the jargon.

Any help would be greatly appreciated.
