Subject: [Qemu-devel] [PATCH v2 03/12] vl: Fix latent bug with -global and onboard devices
Date: Thu,  7 Mar 2019 18:23:52 +0100	[thread overview]
Message-ID: <20190307172401.29451-4-armbru@redhat.com> (raw)
In-Reply-To: <20190307172401.29451-1-armbru@redhat.com>

main() registers the user's -global only after we create the machine
object, i.e. too late for devices created in the machine's
.instance_init().

Fortunately, we know the bug is only latent: the commit before
previous fixed a bug that would've crashed any attempt to create a
device in an .instance_init().
