libvirt need set QEMU_CAPS_PCI_MULTIBUS for PowerPC for QEMU>=2.0.
if (qemuCaps->arch == VIR_ARCH_PPC || qemuCaps->arch == VIR_ARCH_PPC64)
virQEMUCapsSet(qemuCaps, QEMU_CAPS_PCI_MULTIBUS);
But for QEMU <2.0, how should we judge the machines with different PCI bus name?
BTW, libvirt maintainer would like a general solution for all the architecture
not limited to PowerPC.
