+
+ This argument can be repeated multiple times. Its main use is to allow network interfaces be created
+ as ``enoX`` on Linux, with X being the instance number, instead of the name depending on the interface
+ position on the PCI bus.
+
+ Here is an example of use:
+
+ .. parsed-literal::
+
+ -netdev user,id=internet \\
+ -device virtio-net-pci,mac=50:54:00:00:00:42,netdev=internet,id=internet-dev \\
+ -smbios type=41,designation='Onboard LAN',instance=1,kind=ethernet,pcidev=internet-dev
+
+ In the guest OS, the device should then appear as ``eno1``:
+
+ ..parsed-literal::
+
+ $ ip -brief l
+ lo UNKNOWN 00:00:00:00:00:00 <LOOPBACK,UP,LOWER_UP>
+ eno1 UP 50:54:00:00:00:42 <BROADCAST,MULTICAST,UP,LOWER_UP>
+
+ Currently, the PCI device has to be attached to the root bus.
