The essence of Xen is para-virtualisation. What that actually means is "don't virtualise the real hardware because it is hard but provide a different efficient interface and do so in a secure fashion". Xen now has test support for real hardware virtualisation extensions on upcoming x86 processors so it is becoming more similar as the relevant ideas get into the x86 silicon. With hardware support Xensource have actually demonstrated Windows on Xen, although unlike vmware (which does it the hard way) it can't run Windows virtualised on generic x86 silicon.
