Maybe we can get someone to talk about it.

This statement is incorrect.  KVM comes as a kernel module and a user 
space utility built on qemu.

Xen is highly intrusive in the Linux kernel and is not a mere module to 
load.  Xen is vasty different from KVM and VMware in this respect.

VMware loads a slew of kernel modules -> vmnet, vmmon, etc.  So, KVM is 
more like VMware I would say,  but it is free :-)  So, if you have some 
corporate guys coming to you saying "check out this Xen thing", because 
they only know the buzz, you should probably ditch Xen and start with 
KVM.  You will be ahead of the game when Xen is dumped next year...
