It's tempting to use separate command lines to specify their behavior. e.g., in the following example, the cpu-pm command is quietly overwritten, and it's not easy to notice it without careful inspection. --overcommit mem-lock=on --overcommit cpu-pm=on Fixes: c8c9dc42b7ca ("Remove the deprecated -realtime option") Suggested-by: Thomas Huth Signed-off-by: Zide Chen Reviewed-by: Thomas Huth Reviewed-by: Zhao Liu Reviewed-by: Igor Mammedov Reviewed-by: Michael Tokarev Signed-off-by: Michael Tokarev --- system/vl.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/system/vl.c b/system/vl.c index cfcb674425..4dc862652f 100644 --- a/system/vl.c +++ b/system/vl.c @@ -3546,8 +3546,8 @@ void qemu_init(int argc, char **argv) if (!opts) { exit(1); } - enable_mlock = qemu_opt_get_bool(opts, "mem-lock", false); - enable_cpu_pm = qemu_opt_get_bool(opts, "cpu-pm", false); + enable_mlock = qemu_opt_get_bool(opts, "mem-lock", enable_mlock); + enable_cpu_pm = qemu_opt_get_bool(opts, "cpu-pm", enable_cpu_pm); break; case QEMU_OPTION_compat: {
