 Something similar to vmware's virtual center. Maybe for geeks it is fun to 
have a lot of tiny tools to play around with, but I think the end user needs a 
system that will do everything out of the box. And clearly the person who posed 
the original question was expecting this. And it is also clear that xen 
currently doesn't have such a tool, not open source at least.

 Again, I am not saying that the xen should provide it, but that there do exist 
a gap that needs to be filled--that is a tool that will do everything, 
including configure the hostname, network of the virtual machine from the dom0 
automatically.

 Of course, one has to always the keep the priorities in perspective at all 
times, and not get sidetracked on unnecessary features. But even if are 
considering core virtualization, I think xen should provide some mechanism to 
directly communicate with the domU using the domU's name as the identifier.

 Does any of them provide the capabilities of virtual center? Or at least the 
ability to configure the virtual machines from dom0?

:-) Despite your personal antagonism, you can't ignore that it does exist, and 
it does serve some purpose (otherwise people won't pay for it). So rather than 
dismissing it, maybe you should mimic its features in open source.
