From 4060e671c33679198d777558bf7c3750610e0f3d Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Wed, 28 Feb 2018 06:38:23 +0100 Subject: balloon: Fix documentation of the --balloon parameter and deprecate it There are two issues with the documentation of the --balloon parameter: First, "--balloon none" is simply doing nothing. Even if a machine had a balloon device by default, this option is not disabling anything, it is simply ignored. Thus let's simply drop this option from the documentation to avoid to confuse the users (but keep the code in vl.c for backward compatibility). Second, the documentation claims that "--balloon virtio" is the default mode, but this is not true anymore since commit 382f074371f7dc32a34. Since that commit, the option also has no real use case anymore, since you can simply use "--device virtio-balloon" nowadays instead. Thus to simplify our complex parameter zoo a little bit, let's deprecate the the parameter now and tell the user to use "--device virtio-balloon" instead.
