You've also got a frozen, multi-vendor binary interface, which was the straw which broke our original intentions for VMI. Try as you can, you cannot get around this, and there is just no way that list of players are going to remain friendly and happy with each other (embrace, extend, conquer, anyone?). There are already differences with VMI / lhype and Xen (shadow vs. direct page tables), and also with KVM vs VMI / Xen / lhype (required HVM vs optional HVM). Like it or not, incompatible changes will happen, and with no official standard body to mediate so that it can't be dominated by one party, I don't see how it can work. Which is why I now prefer the flexible in kernel API of paravirt-ops.
