[Qemu-trivial] [RFC PATCH 4/4] qemu-options: Do not show -enable-kvm and

From: Thomas Huth
Subject: [Qemu-trivial] [RFC PATCH 4/4] qemu-options: Do not show -enable-kvm and -enable-hax in the docs anymore
Date: Wed, 13 Jun 2018 07:05:21 +0200

We've got three ways of enabling an accelerator: -machine accel=xyz,
-accel xyz and -enable-xyz. For new QEMU users, this must be very
confusing ("Which one do I have to use? Is there a difference between
the options?"). While -enable-kvm was useful in the past, there is no
real good reason for using it anymore today ("-accel kvm" is even less
to type than "-enable-kvm"), so let's decrease the confusing amount of
options in our documenation a little bit by removing the -enable-xyz
here. Note that the option itself is neither removed nor marked as
deprecated - since -enable-kvm is likely used in a lot of scripts and
since its code is easy to maintain, we should keep it around to avoid
to break old setups.

 PS: I guess Paolo won't like this patch ... let's try it anyway ;-)
