From 47c8ca533e502955a4e1b24056639c79500ab8f8 Mon Sep 17 00:00:00 2001 From: Marcel Apfelbaum Date: Wed, 4 Feb 2015 17:43:54 +0200 Subject: [PATCH] machine: query dump-guest-core machine property Running qemu-bin ... -machine pc,dump-guest-core=on leads to crash: x86_64-softmmu/qemu-system-x86_64 -machine pc,dump-guest-core=on qemu-system-x86_64: qemu/util/qemu-option.c:387: qemu_opt_get_bool_helper: Assertion `opt->desc && opt->desc->type == QEMU_OPT_BOOL' failed. Aborted (core dumped) This happens because the commit e79d5a6 ("machine: remove qemu_machine_opts global list") removed the global option descriptions and moved them to MachineState's QOM properties. Fix this by querying machine properties through designated wrappers. Signed-off-by: Marcel Apfelbaum Acked-by: Michael S. Tsirkin Signed-off-by: Michael S.
