I've researched and checked the obvious AMD processor with the enable nested flag, running a kvm guest with the nesting support enabled etc. which did allow me to add the Hyper-V role to the VM but when it reboots, the machine hardware lists a problem with the VM machine bus and no hyper-v VMs can be created. From what I've read through from lurking on the list and reading the archives, I'm not sure whether the problem is that KVM is not ready to support Hyper-V yet or if I'm doing it wrong. I'd be very thankful if someone could say if I'm hoping for too much right now or point me where to go to find some details on what I'm doing wrong and how to do it right.
