My comment is not related to your patch for QEMU.
I mean that we need add version detection in libvirt like below after your
patch accepted:
libvirt/src/qemu/qemu_capabilities.c: virQEMUCapsComputeCmdFlags()
...
if (version >= 9000)
virQEMUCapsSet(qemuCaps, QEMU_CAPS_VNC_COLON);
if (is_kvm && (version >= 10000 || kvm_version >= 74))
virQEMUCapsSet(qemuCaps, QEMU_CAPS_VNET_HDR);
...
We need judge which version of QEMU support 'pci' for pseries and which version
support 'pci.0'.
