Thanks.
You are right. I think this is what you are talking about.
for i in `seq 0 3`; do virsh nodedev-dumpxml pci_0000_25_10_$i;done | grep
address;
pci_0000_25_10_0
<address domain='0x0000' bus='0x25' slot='0x00' function='0x0'/>
pci_0000_25_10_1
<address domain='0x0000' bus='0x25' slot='0x00' function='0x1'/>
pci_0000_25_10_2
<address domain='0x0000' bus='0x25' slot='0x00' function='0x0'/>
pci_0000_25_10_3
<address domain='0x0000' bus='0x25' slot='0x00' function='0x1'/>
