-@item -n script
-Set TUN/TAP network init script [default=/etc/qemu-ifup]. This script
-is launched to configure the host network interface (usually tun0)
-corresponding to the virtual NE2000 card.
+@item -net nic[,vlan=n][,macaddr=addr]
+Create a new Network Interface Card and connect it to VLAN @var{n} (@var{n}
+= 0 is the default). The NIC is currently an NE2000 on the PC
+target. Optionally, the MAC address can be changed. If no
+@option{-net} option is specified, a single NIC is created.
+
+@item -net user[,vlan=n]
+Use the user mode network stack which requires not administrator
+priviledge to run. This is the default if no @option{-net} option is
+specified.
+
+@item -net tap[,vlan=n][,fd=h][,ifname=name][,script=file]
+Connect the host TAP network interface @var{name} to VLAN @var{n} and
+use the network script @var{file} to configure it. The default
+network script is @file{/etc/qemu-ifup}. If @var{name} is not
+provided, the OS automatically provides one. @option{fd=h} can be
+used to specify the handle of an already opened host TAP interface. Example:
