If I read the git history correctly, there were two patches changing pci bus names for ppc in this release, not just one: commit 1b8601b0ea0b91467561e0bbddd52a833e4b2b1a Author: Alexey Kardashevskiy <a...@ozlabs.ru> AuthorDate: 2014-03-06 14:11:00 +1100 Commit: Andreas Färber <afaer...@suse.de> CommitDate: 2014-03-12 20:13:02 +0100 spapr-pci: Change the default PCI bus naming Previously libvirt required the first/default PCI bus to have name "pci". Since QEMU can support multiple buses now, libvirt wants "pci.0" now. This removes custom bus name and lets QEMU make up default names.

The big downside to calling it different from anyone else is that tools that pass -device get confused. They are looking for a bus "pci.0" rather than "pci". To make life easier for everyone, let's just drop the name override. Signed-off-by: Alexander Graf <ag...@suse.de> Jan
