Public bug reported: == Comment: #0 - MIKHAIL S. MEDVEDEV <[email protected]> - 2017-03-03 14:21:43 == ---Problem Description--- On ppc64el qemu the order of device scanning was recently changed, causing device names to be in reverse order compared to e.g. x86. This is creating a need for all sorts of work arounds to make the code that assumes certain order of devices to work on Power.
The fix has been proposed and it appears it would go into Qemu 2.9, see [1]. It might be awhile until qemu 2.9 gets widely adopted as default. It would be beneficial if the fix can be backported to an earlier versions of Qemu.
