Subject: [Qemu-devel] [PULL 03/13] i386: Return migration-safe field on query-cpu-definitions
Date: Mon, 23 Jan 2017 21:27:28 -0200	[thread overview]
Message-ID: <20170123232738.20796-4-ehabkost@redhat.com> (raw)
In-Reply-To: <20170123232738.20796-1-ehabkost@redhat.com>

Return the migration-safe field on query-cpu-definitions. All CPU
models in x86 are migration-safe except "host".
