I'm not seeing the expected results
Thanks in advance!

4 Now detach 05.10.0 and 05.11.0 from the host:
# virsh nodedev-dettach pci_0000_05_10_0
Device pci_0000_05_10_0 dettached
# virsh nodedev-dettach pci_0000_05_11_0
Device pci_0000_05_11_0 dettached
5. Get the host, slot, function information:
# virsh nodedev-dumpxml pci_0000_05_10_0|grep -e bus -e slot -e fun |head -3
<bus>5</bus>
<slot>16</slot>
<function>0</function>
# virsh nodedev-dumpxml pci_0000_05_11_0|grep -e bus -e slot -e fun |head -3
<bus>5</bus>
<slot>17</slot>
<function>0</function>
