Hi Peter,
     Follow your advice, I have complied the Qemu v2.6.
stack@u202158:~$ kvm --version
QEMU emulator version 2.6.50 (v2.6.0-1280-g6f1d2d1-dirty), Copyright (c)
2003-2008 Fabrice Bellard
     With this newest version, I use virt-manager to create the guest , the
xml file is in the attachment. But the Qemu return error when creating:
     *error: internal error: process exited while connecting to monitor:
qemu-system-aarch64: -device
pci-bridge,chassis_nr=2,id=pci,bus=pci,addr=0x1: Duplicate ID 'pci' for
device*

     The guest xml file in in attachment. But the XML worked when Qemu is
v2.4.0.
      Also I delete the items in the xml :
  -  <controller type='pci' index='0' model='pcie-root'/>
  -  <controller type='pci' index='1' model='dmi-to-pci-bridge'>
  -    <model name='i82801b11-bridge'/>
  -    <address type='pci' domain='0x0000' bus='0x00' slot='0x01'
function='0x0'/>
  -  </controller>
  -  <controller type='pci' index='2' model='pci-bridge'>
  -    <model name='pci-bridge'/>
  -    <target chassisNr='2'/>
  -    <address type='pci' domain='0x0000' bus='0x01' slot='0x01'
function='0x0'/>
  -  </controller>
      Using virsh create guest.xml, got the error too :
      *error: internal error: process exited while connecting to monitor:
qemu-system-aarch64: -device
pci-bridge,chassis_nr=2,id=pci,bus=pci,addr=0x1: Duplicate ID 'pci' for
device.*
My test machine is Softiron, with AMD* ARM64 *server CPU. The  libvirt
version is 1.3.1

     Kindly need your help. You will be really appreciated :-)
     Big Thanks~

Best Regards,
Kevin Zhao
