@item -m megs
Set virtual RAM size to @var{megs} megabytes. Default is 128 MB.
-@item -initrd file
-Use @var{file} as initial ram disk.

@item -nographic
Normally, QEMU uses SDL to display the VGA output. With this option,
Use the user mode network stack. This is the default if no tun/tap
network init script is found.
+@item -tftp prefix
+When using the user mode network stack, activate a built-in TFTP
+server. All filenames beginning with @var{prefix} can be downloaded
+from the host to the guest using a TFTP client. The TFTP client on the
+guest must be configured in binary mode (use the command @code{bin} of
+the Unix TFTP client). The host IP address on the guest is as usual
+10.0.2.2.
+
+@item -redir [tcp|udp]:host-port:[guest-host]:guest-port
+
+When using the user mode network stack, redirect incoming TCP or UDP
+connections to the host port @var{host-port} to the guest
+@var{guest-host} on guest port @var{guest-port}. If @var{guest-host}
+is not specified, its value is 10.0.2.15 (default address given by the
+built-in DHCP server).
+
+For example, to redirect host X11 connection from screen 1 to guest
+screen 0, use the following:
+
+@example
+# on the host
+qemu -redir tcp:6001::6000 [...]
+# this host xterm should open in the guest X11 server
+xterm -display :1
+@end example
+
+To redirect telnet connections from host port 5555 to telnet port on
+the guest, use the following:
+
+@example
+# on the host
+qemu -redir tcp:5555::23 [...]
+telnet localhost 5555
+@end example
+
+Then when you use on the host @code{telnet localhost 5555}, you
+connect to the guest telnet server.
+
@item -dummy-net
Use the dummy network stack: no packet will be received by the network
cards.
The default device is @code{vc} in graphical mode and @code{stdio} in
non graphical mode.
+This option can be used several times to simulate up to 4 serials
+ports.
+
@item -monitor dev
Redirect the monitor to host device @var{dev} (same devices as the
serial port).
would require root priviledges. It means you can only ping the local
router (10.0.2.2).
-The user mode network is currently only supported on a Unix host.
+When using the built-in TFTP server, the router is also the TFTP
+server.
+
+When using the @option{-redir} option, TCP or UDP connections can be
+redirected from the host to the guest. It allows for example to
+redirect X11, telnet or SSH connections.
