OpenVZ does not provide any web interfaces. Of course you can use, say,
Webmin or something like this.
Or, if you want all the features of OpenVZ plus control panels plus much
more -- you can buy Virtuozzo.

I am not sure what you mean by "from old to new IPs". Do you want to
change the IP address(es) of the VPS? Do you want to clone a VPS, and
give a different IP to the clone?

In very short: http://openvz.org/documentation/tech/virtualization
In very short: the difference is Xen runs *multiple* kernels on top of
the hypervisor, while OpenVZ enables multiple Virtual Environments (VEs,
otherwise known as VPSs) on top of the *single* kernel. Single kernel
approach gives close-to-native performance and much better density
(number of VEs per server), also there are other benefits like higher
scalability (VE is as scalable as ordinary Linux) and the fact that you
can change/"resize" a VE dynamically -- say, you can give it more or
less RAM without any need to reboot.
From the other side, Xen makes possible to run *different* kernels, so
it's the way to go if you want different OSs on your server.

As I am very subjective here you can't rely on my words for it. :)
Some people say OpenVZ is easier to install and use (say here:
http://forum.openvz.org/index.php?t=rview&goto=3119#msg_ 3119).
Sorry I do not know much about control panels.
