Re: [libvirt] [PATCH] Reserve PCI addresses 3 and 4 on qemu-system-ppc

On PPC emulated by recent versions of qemu, PCI-bus 0 already has a macio connected in slot 3 and OHCI on slot 4. Reference: - https://bugzilla.redhat.com/show_bug.cgi?id=667345 Signed-off-by: Niels de Vos <ndevos(a)redhat.com&gt; --- Imho this patch is relatively ugly. Unfortunately I did not find a better way of changing the reserved PCI-addresses on a per architecture basis. It can well be that qemuAssignDevicePCISlots() needs to be updated for other architectures as well. A more modular/dynamic approach might be more suitable. Feel free to suggest an alternative way to solve this.
