Re: [Qemu-devel] [PATCH] spapr-pci: change the default PCI bus naming

[address@hidden]

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.
