From cba0e7796be18f61f43e60bff6bff986851e359a Mon Sep 17 00:00:00 2001 From: Greg Kurz Date: Tue, 23 Feb 2016 17:47:59 +0100 Subject: [PATCH] spapr: disable vmdesc submission for old machines Since QEMU 2.3, we have a vmdesc section in the migration stream. This section is not mandatory but when migrating a pseries-2.2 machine from QEMU 2.2, you get a warning at the destination: qemu-system-ppc64: Expected vmdescription section, but got 0 The warning goes away if we decide to skip vmdesc as well for older pseries, like it is already done for pc's. This can only be observed with -cpu POWER7 because POWER8 cannot migrate from QEMU 2.2 to 2.3 (insns_flags2 mismatch).
