Hi, Yeah, I am aware of this option. But the point where I am concerned is that if Windows VM is running in QEMU 1.0 with pc-model 1.0 and then I upgrade the QEMU to 2.0 and I specify machine as pc-1.2, then Windows will see this as change in hardware and complain about the license.
Sorry, if my understanding is wrong here or i am missing something.
