Support is planned. Of course it makes sense to implement such interfaces -- if they are well-accepted. In fact this is para-virtualization: Make the guest aware that it runs inside a VM. Kind regards, Frank [Geoff Nordli] Frank, are you saying it would be compatible with Hyper-V virtual machines? If so, that would be amazing to be able to move a machine seamlessly from a Hyper-V server.
