[Qemu-devel] [PULL 9/9] vl: exit if a bad property value is passed to -global

[Eduardo Habkost]

From: Greg Kurz <address@hidden>

When passing '-global driver=host-powerpc64-cpu,property=compat,value=foo'
on the command line, without this patch, we get the following warning per
device (which means many lines if the guests has many cpus):

qemu-system-ppc64: Warning: can't apply global host-powerpc64-cpu.compat=foo:
    Invalid compatibility mode "foo"

... and QEMU continues execution, ignoring the property.

With this patch, we get a single line:

qemu-system-ppc64: can't apply global host-powerpc64-cpu.compat=foo:
    Invalid compatibility mode "foo"

... and QEMU exits.

The previous behavior is kept for hotplugged devices since we don't want
QEMU to exit when doing device_add.
