From dcf389cbc84c2b714d49887775918c5f03f73864 Mon Sep 17 00:00:00 2001 From: Fabiano Rosas Date: Wed, 18 Oct 2023 16:27:35 -0300 Subject: [PATCH] tests/qtest/migration: Introduce find_common_machine_version When using two different QEMU binaries for migration testing, we'll need to find what is the machine version that will work with both binaries. Add a helper for that.
