Hi

you can test it if add
'xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0' (with ') to
the <domain type='kvm'> line, and

  <qemu:commandline>
   <qemu:arg value='-device'/>
   <qemu:arg value='ioh3420,bus=pcie.0,addr=1c.0,port=1,chassis=1,id=root.1'/>
   <qemu:arg value='-device'/>
   <qemu:arg value='vfio-pci,host=01:00.0,bus=root.1,addr=00.0,romfile=/root/qemu/rom/amd285.rom'/>
   <qemu:arg value='-device'/>
   <qemu:arg value='vfio-pci,host=01:00.1,bus=pcie.0,addr=10.0'/>
 </qemu:commandline>

just before </domain> line
