Virt-manager has this code:
virtManager/object/nodedev.py:34:
return "%s %s %s" % (devstr, xmlobj.vendor_name, xmlobj.product_name)
virtinst/nodedev.py:147:
product_name = XMLProperty("./capability/product")
So it is expecting an XML protperty to provide the PCI product name.
But the information provided by libvirt looks like this:
Device: pci_0000_00_1f_3
<device>
<name>pci_0000_00_1f_3</name>
<path>/sys/devices/pci0000:00/0000:00:1f.3</path>
<parent>computer</parent>
<driver>
<name>sof-audio-pci-intel-mtl</name>
</driver>
<capability type='pci'>
<class>0x040100</class>
<domain>0</domain>
<bus>0</bus>
<slot>31</slot>
<function>3</function>
<product id='0x7728'/>
<vendor id='0x8086'/>
<iommuGroup number='14'>
<address domain='0x0000' bus='0x00' slot='0x1f' function='0x0'/>
<address domain='0x0000' bus='0x00' slot='0x1f' function='0x5'/>
<address domain='0x0000' bus='0x00' slot='0x1f' function='0x3'/>
<address domain='0x0000' bus='0x00' slot='0x1f' function='0x6'/>
<address domain='0x0000' bus='0x00' slot='0x1f' function='0x4'/>
</iommuGroup>
</capability>
</device>
I have appended pci_dev_list.c which can be compiled with
gcc -o pci_dev_list pci_dev_list.c -lvirt
It is libvirt that creates the XML and not virt-manager. Virt-manager
cannot display information that libvirt does not provide. So this bug
should be filed against libvirt.
