The udev driver does not update a PCI device with its SR-IOV capabilities,
when applicable, the way the hal driver does. As a result, dumping the
device's XML will not include the relevant physical or virtual function
information.
With this patch, the XML is correct:
# virsh nodedev-dumpxml pci_0000_09_00_0
<device>
<name>pci_0000_09_00_0</name>

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
