Consider this scenario: I change the MAC and the host at some point;
no reactivation required. 10 months later I simply upgrade QEMU from
0.9.0 to 0.9.1 and change nothing else; reactivation is required. This
is not something an enduser would expect.
Another way to see it is that I was in control of the MAC and host
change, but not of the IDENTIFY replies. An enduser should always be
in control of the "hardware changes" he makes to a guest.
Also, I believe (but am not sure) that if I had installed Windows on
QEMU version A and upgraded to version B to C to D, then Windows would
require reactivation after the upgrade to D because it would be seen
as the 3rd "hardware change".
