I'm aware of the fact that likely a lot of users are still using
-enable-kvm, and I did not mean that we should remove it soon yet. But
IMHO we should start now to inform the users that they should slowly
switch to the better option "-accel" instead, so that we could maybe
remove this "-enable-xxx" stuff sometime in the distant future (let's
say QEMU v4.0?).
