Description of problem:
Attempting to create a ppc vm fails with error message and traceback.
Version-Release number of selected component (if applicable):
virt-manager version 1.0.1
libvirt version 126.96.36.199
qemu version 1.6.2
Steps to Reproduce:
1. Attempt to create a machine and set architecture to ppc.
2. Add an install image (iso) for PPC.
3. Click "begin installation".
Unable to complete install: 'internal error: process exited while connecting to monitor: qemu-system-ppc: -device piix3-usb-uhci,id=usb,bus=pci,addr=0x2: Bus 'pci' not found
and this traceback:
Traceback (most recent call last):

Working PPC emulation.
This bug was originally reported for Fedora 14 by Helmut Schlattl and was previously closed after some initial efforts due to the EOL of Fedora 14.
My apologies, I cannot provide libvirt xml because virt-manager does not create it as far as I can tell. It is not present anywhaere in /etc/libvirt, at any rate.
The only powerpc version that libvirt likely works with is qemu-system-ppc64 -M pseries, the rest very likely libvirt has incorrect assumptions. FWIW that's what virt-manager will select by default if you choose arch=ppc64. Anything else at this point is probably better served by googling for a working qemu command line and using it manually.
The bus not found error should be fixed in libvirt 1.2.4 by:

Fix pci bus naming for PPC
Recent discussions around naming of 'pci' vs 'pci.0' for PPC
made me go back and look at the PPC emulator in every historical
version of QEMU since 1.0. The results were worse than I imagined.
This patch adds the logic required to make libvirt work with PPC
correctly with naming variations across all versions & machine

Oh, hmm, I was confused, I assumed -M bamboo didn't have PCI. Was thinking of ARM :)
Though I still wouldn't be surprised if virt-manager or libvirt still have other issues generating a working -M bamboo command line
