It does sometimes happen that there is no state. For example it could be
an MSR that we are already getting in and out of KVM. However, it is way
more common that you have to add support for reading/writing the MSR in
KVM as well, and then teach QEMU's target-i386/kvm.c about it as well.
It's hard to say without knowing exactly what the feature is about...
Is there an architecture manual out there that documents it?
Paolo
