^^^^^^^^^^^^
I think we should remove the line above.

The output of "info network"
(qemu) info network
Devices not on any VLAN:
   e1000.0: type=nic,model=e1000,macaddr=52:54:00:12:34:56
    \ hub0port1: type=(null),
hub 0
     port 1 peer e1000.0
     port 0 peer bridge.0

The original output:
(qemu) info network
VLAN 0 devices:
   bridge.0: type=tap,helper=./qemu-bridge-helper,br=virbr0
   e1000.0: type=nic,model=e1000,macaddr=52:54:00:12:34:56
Devices not on any VLAN:
