From 3d5e90a50bd4ffa199166e01a365f5c5995534ae Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Mon, 23 Sep 2019 14:00:29 +0200 Subject: [PATCH] Disallow colons in the parameter of "-accel" Everybody who used something like "-machine accel=kvm:tcg" in the past might be tempted to specify a similar list with the -accel parameter, too, for example "-accel kvm:tcg". However, this is not how this options is thought to be used, since each "-accel" should only take care of one specific accelerator. In the long run, we really should rework the "-accel" code completely, so that it does not set "-machine accel=..." anymore internally, but is completely independent from "-machine". For the short run, let's make sure that users cannot use "-accel xyz:tcg", so that we avoid that we have to deal with such cases in the wild later.
