Syncing documentation vs. -help vs. qemu_options table 

Try to keep documentation about command line switches, -help text and
qemu_options table synchronized. 

In true Qemu tradition, an include file is generated from single .hx file
containing all relevant information in one place. The include file is
parsed once for getting the enums, another time for getopt tables and
hird time for help messages. Texi documentation for the options is
generated from the same .hx file.

@ -224,980 +224,7 @@ usage: qemu [options] [@var{disk_image}]
@var{disk_image} is a raw hard disk image for IDE hard disk 0. Some
targets do not need a disk image.
General options:
@table @option
@item -h
Display help and exit
@item -M @var{machine}
Select the emulated @var{machine} (@code{-M ?} for list)
@item -cpu @var{model}
Select CPU model (-cpu ? for list and additional feature selection)
@item -smp @var{n}
Simulate an SMP system with @var{n} CPUs. On the PC target, up to 255
CPUs are supported. On Sparc32 target, Linux limits the number of usable CPUs
to 4.
@item -fda @var{file}
@item -fdb @var{file}
Use @var{file} as floppy disk 0/1 image (@pxref{disk_images}). You can
use the host floppy by using @file{/dev/fd0} as filename (@pxref{host_drives}).
@item -hda @var{file}
@item -hdb @var{file}
@item -hdc @var{file}
@item -hdd @var{file}
Use @var{file} as hard disk 0, 1, 2 or 3 image (@pxref{disk_images}).
@item -cdrom @var{file}
Use @var{file} as CD-ROM image (you cannot use @option{-hdc} and
@option{-cdrom} at the same time). You can use the host CD-ROM by
using @file{/dev/cdrom} as filename (@pxref{host_drives}).
@item -drive @var{option}[,@var{option}[,@var{option}[,...]]]
Define a new drive. Valid options are:
@table @code
@item file=@var{file}
This option defines which disk image (@pxref{disk_images}) to use with
this drive. If the filename contains comma, you must double it
(for instance, "file=my,,file" to use file "my,file").
@item if=@var{interface}
This option defines on which type on interface the drive is connected.
Available types are: ide, scsi, sd, mtd, floppy, pflash, virtio.
@item bus=@var{bus},unit=@var{unit}
These options define where is connected the drive by defining the bus number and
the unit id.
@item index=@var{index}
This option defines where is connected the drive by using an index in the list
of available connectors of a given interface type.
@item media=@var{media}
This option defines the type of the media: disk or cdrom.
@item cyls=@var{c},heads=@var{h},secs=@var{s}[,trans=@var{t}]
These options have the same definition as they have in @option{-hdachs}.
@item snapshot=@var{snapshot}
@var{snapshot} is "on" or "off" and allows to enable snapshot for given drive (see @option{-snapshot}).
@item cache=@var{cache}
@var{cache} is "none", "writeback", or "writethrough" and controls how the host cache is used to access block data.
@item format=@var{format}
Specify which disk @var{format} will be used rather than detecting
the format. Can be used to specifiy format=raw to avoid interpreting
an untrusted format header.
@item serial=@var{serial}
This option specifies the serial number to assign to the device.
@end table
By default, writethrough caching is used for all block device. This means that
the host page cache will be used to read and write data but write notification
will be sent to the guest only when the data has been reported as written by
the storage subsystem.
Writeback caching will report data writes as completed as soon as the data is
present in the host page cache. This is safe as long as you trust your host.
If your host crashes or loses power, then the guest may experience data
corruption. When using the @option{-snapshot} option, writeback caching is
used by default.
The host page can be avoided entirely with @option{cache=none}. This will
attempt to do disk IO directly to the guests memory. QEMU may still perform
an internal copy of the data.
Some block drivers perform badly with @option{cache=writethrough}, most notably,
qcow2. If performance is more important than correctness,
@option{cache=writeback} should be used with qcow2. By default, if no explicit
caching is specified for a qcow2 disk image, @option{cache=writeback} will be
used. For all other disk types, @option{cache=writethrough} is the default.
Instead of @option{-cdrom} you can use:
@example
qemu -drive file=file,index=2,media=cdrom
@end example
Instead of @option{-hda}, @option{-hdb}, @option{-hdc}, @option{-hdd}, you can
use:
@example
qemu -drive file=file,index=0,media=disk
qemu -drive file=file,index=1,media=disk
qemu -drive file=file,index=2,media=disk
qemu -drive file=file,index=3,media=disk
@end example
You can connect a CDROM to the slave of ide0:
@example
qemu -drive file=file,if=ide,index=1,media=cdrom
@end example
If you don't specify the "file=" argument, you define an empty drive:
@example
qemu -drive if=ide,index=1,media=cdrom
@end example
You can connect a SCSI disk with unit ID 6 on the bus #0:
@example
qemu -drive file=file,if=scsi,bus=0,unit=6
@end example
Instead of @option{-fda}, @option{-fdb}, you can use:
@example
qemu -drive file=file,index=0,if=floppy
qemu -drive file=file,index=1,if=floppy
@end example
By default, @var{interface} is "ide" and @var{index} is automatically
incremented:
@example
qemu -drive file=a -drive file=b"
@end example
is interpreted like:
@example
qemu -hda a -hdb b
@end example
@item -mtdblock file
Use 'file' as on-board Flash memory image.
@item -sd file
Use 'file' as SecureDigital card image.
@item -pflash file
Use 'file' as a parallel flash image.
@item -boot [a|c|d|n]
Boot on floppy (a), hard disk (c), CD-ROM (d), or Etherboot (n). Hard disk boot
is the default.
@item -snapshot
Write to temporary files instead of disk image files. In this case,
the raw disk image you use is not written back. You can however force
the write back by pressing @key{C-a s} (@pxref{disk_images}).
@item -m @var{megs}
Set virtual RAM size to @var{megs} megabytes. Default is 128 MiB. Optionally,
a suffix of ``M'' or ``G'' can be used to signify a value in megabytes or
gigabytes respectively.
@item -k @var{language}
Use keyboard layout @var{language} (for example @code{fr} for
French). This option is only needed where it is not easy to get raw PC
keycodes (e.g. on Macs, with some X11 servers or with a VNC
display). You don't normally need to use it on PC/Linux or PC/Windows
hosts.
The available layouts are:
@example
ar de-ch es fo fr-ca hu ja mk no pt-br sv
da en-gb et fr fr-ch is lt nl pl ru th
de en-us fi fr-be hr it lv nl-be pt sl tr
@end example
The default is @code{en-us}.
@item -audio-help
Will show the audio subsystem help: list of drivers, tunable
parameters.
@item -soundhw @var{card1}[,@var{card2},...] or -soundhw all
Enable audio and selected sound hardware. Use ? to print all
available sound hardware.
@example
qemu -soundhw sb16,adlib disk.img
qemu -soundhw es1370 disk.img
qemu -soundhw ac97 disk.img
qemu -soundhw all disk.img
qemu -soundhw ?
@end example
Note that Linux's i810_audio OSS kernel (for AC97) module might
require manually specifying clocking.
@example
modprobe i810_audio clocking=48000
@end example
@end table
USB options:
@table @option
@item -usb
Enable the USB driver (will be the default soon)
@item -usbdevice @var{devname}
Add the USB device @var{devname}. @xref{usb_devices}.
@table @code
@item mouse
Virtual Mouse. This will override the PS/2 mouse emulation when activated.
@item tablet
Pointer device that uses absolute coordinates (like a touchscreen). This
means qemu is able to report the mouse position without having to grab the
mouse. Also overrides the PS/2 mouse emulation when activated.
@item disk:[format=@var{format}]:file
Mass storage device based on file. The optional @var{format} argument
will be used rather than detecting the format. Can be used to specifiy
format=raw to avoid interpreting an untrusted format header.
@item host:bus.addr
Pass through the host device identified by bus.addr (Linux only).
@item host:vendor_id:product_id
Pass through the host device identified by vendor_id:product_id (Linux only).
@item serial:[vendorid=@var{vendor_id}][,productid=@var{product_id}]:@var{dev}
Serial converter to host character device @var{dev}, see @code{-serial} for the
available devices.
@item braille
Braille device. This will use BrlAPI to display the braille output on a real
or fake device.
@item net:options
Network adapter that supports CDC ethernet and RNDIS protocols.
@end table
@item -name @var{name}
Sets the @var{name} of the guest.
This name will be displayed in the SDL window caption.
The @var{name} will also be used for the VNC server.
@item -uuid @var{uuid}
Set system UUID.
@end table
Display options:
@table @option
@item -nographic
Normally, QEMU uses SDL to display the VGA output. With this option,
you can totally disable graphical output so that QEMU is a simple
command line application. The emulated serial port is redirected on
the console. Therefore, you can still use QEMU to debug a Linux kernel
with a serial console.
@item -curses
Normally, QEMU uses SDL to display the VGA output. With this option,
QEMU can display the VGA output when in text mode using a
curses/ncurses interface. Nothing is displayed in graphical mode.
@item -no-frame
Do not use decorations for SDL windows and start them using the whole
available screen space. This makes the using QEMU in a dedicated desktop
workspace more convenient.
@item -alt-grab
Use Ctrl-Alt-Shift to grab mouse (instead of Ctrl-Alt).
@item -no-quit
Disable SDL window close capability.
@item -sdl
Enable SDL.
@item -portrait
Rotate graphical output 90 deg left (only PXA LCD).
@item -vga @var{type}
Select type of VGA card to emulate. Valid values for @var{type} are
@table @code
@item cirrus
Cirrus Logic GD5446 Video card. All Windows versions starting from
Windows 95 should recognize and use this graphic card. For optimal
performances, use 16 bit color depth in the guest and the host OS.
(This one is the default)
@item std
Standard VGA card with Bochs VBE extensions. If your guest OS
supports the VESA 2.0 VBE extensions (e.g. Windows XP) and if you want
to use high resolution modes (>= 1280x1024x16) then you should use
this option.
@item vmware
VMWare SVGA-II compatible adapter. Use it if you have sufficiently
recent XFree86/XOrg server or Windows guest with a driver for this
card.
@item none
Disable VGA card.
@end table
@item -full-screen
Start in full screen.
@item -vnc @var{display}[,@var{option}[,@var{option}[,...]]]
Normally, QEMU uses SDL to display the VGA output. With this option,
you can have QEMU listen on VNC display @var{display} and redirect the VGA
display over the VNC session. It is very useful to enable the usb
tablet device when using this option (option @option{-usbdevice
tablet}). When using the VNC display, you must use the @option{-k}
parameter to set the keyboard layout if you are not using en-us. Valid
syntax for the @var{display} is
@table @code
@item @var{host}:@var{d}
TCP connections will only be allowed from @var{host} on display @var{d}.
By convention the TCP port is 5900+@var{d}. Optionally, @var{host} can
be omitted in which case the server will accept connections from any host.
@item @code{unix}:@var{path}
Connections will be allowed over UNIX domain sockets where @var{path} is the
location of a unix socket to listen for connections on.
@item none
VNC is initialized but not started. The monitor @code{change} command
can be used to later start the VNC server.
@end table
Following the @var{display} value there may be one or more @var{option} flags
separated by commas. Valid options are
@table @code
@item reverse
Connect to a listening VNC client via a ``reverse'' connection. The
client is specified by the @var{display}. For reverse network
connections (@var{host}:@var{d},@code{reverse}), the @var{d} argument
is a TCP port number, not a display number.
@item password
Require that password based authentication is used for client connections.
The password must be set separately using the @code{change} command in the
@ref{pcsys_monitor}
@item tls
Require that client use TLS when communicating with the VNC server. This
uses anonymous TLS credentials so is susceptible to a man-in-the-middle
attack. It is recommended that this option be combined with either the
@var{x509} or @var{x509verify} options.
@item x509=@var{/path/to/certificate/dir}
Valid if @option{tls} is specified. Require that x509 credentials are used
for negotiating the TLS session. The server will send its x509 certificate
to the client. It is recommended that a password be set on the VNC server
to provide authentication of the client when this is used. The path following
this option specifies where the x509 certificates are to be loaded from.
See the @ref{vnc_security} section for details on generating certificates.
@item x509verify=@var{/path/to/certificate/dir}
Valid if @option{tls} is specified. Require that x509 credentials are used
for negotiating the TLS session. The server will send its x509 certificate
to the client, and request that the client send its own x509 certificate.
The server will validate the client's certificate against the CA certificate,
and reject clients when validation fails. If the certificate authority is
trusted, this is a sufficient authentication mechanism. You may still wish
to set a password on the VNC server as a second authentication layer. The
path following this option specifies where the x509 certificates are to
be loaded from. See the @ref{vnc_security} section for details on generating
certificates.
@item sasl
Require that the client use SASL to authenticate with the VNC server.
The exact choice of authentication method used is controlled from the
system / user's SASL configuration file for the 'qemu' service. This
is typically found in /etc/sasl2/qemu.conf. If running QEMU as an
unprivileged user, an environment variable SASL_CONF_PATH can be used
to make it search alternate locations for the service config.
While some SASL auth methods can also provide data encryption (eg GSSAPI),
it is recommended that SASL always be combined with the 'tls' and
'x509' settings to enable use of SSL and server certificates. This
ensures a data encryption preventing compromise of authentication
credentials. See the @ref{vnc_security} section for details on using
SASL authentication.
@item acl
Turn on access control lists for checking of the x509 client certificate
and SASL party. For x509 certs, the ACL check is made against the
certificate's distinguished name. This is something that looks like
@code{C=GB,O=ACME,L=Boston,CN=bob}. For SASL party, the ACL check is
made against the username, which depending on the SASL plugin, may
include a realm component, eg @code{bob} or @code{bob@@EXAMPLE.COM}.
When the @option{acl} flag is set, the initial access list will be
empty, with a @code{deny} policy. Thus no one will be allowed to
use the VNC server until the ACLs have been loaded. This can be
achieved using the @code{acl} monitor command.
@end table
@end table
Network options:
@table @option
@item -net nic[,vlan=@var{n}][,macaddr=@var{addr}][,model=@var{type}][,name=@var{name}]
Create a new Network Interface Card and connect it to VLAN @var{n} (@var{n}
= 0 is the default). The NIC is an ne2k_pci by default on the PC
target. Optionally, the MAC address can be changed to @var{addr}
and a @var{name} can be assigned for use in monitor commands. If no
@option{-net} option is specified, a single NIC is created.
Qemu can emulate several different models of network card.
Valid values for @var{type} are
@code{i82551}, @code{i82557b}, @code{i82559er},
@code{ne2k_pci}, @code{ne2k_isa}, @code{pcnet}, @code{rtl8139},
@code{e1000}, @code{smc91c111}, @code{lance} and @code{mcf_fec}.
Not all devices are supported on all targets. Use -net nic,model=?
for a list of available devices for your target.
@item -net user[,vlan=@var{n}][,hostname=@var{name}][,name=@var{name}]
Use the user mode network stack which requires no administrator
privilege to run. @option{hostname=name} can be used to specify the client
hostname reported by the builtin DHCP server.
@item -net channel,@var{port}:@var{dev}
Forward @option{user} TCP connection to port @var{port} to character device @var{dev}
@item -net tap[,vlan=@var{n}][,name=@var{name}][,fd=@var{h}][,ifname=@var{name}][,script=@var{file}][,downscript=@var{dfile}]
Connect the host TAP network interface @var{name} to VLAN @var{n}, use
the network script @var{file} to configure it and the network script
@var{dfile} to deconfigure it. If @var{name} is not provided, the OS
automatically provides one. @option{fd}=@var{h} can be used to specify
the handle of an already opened host TAP interface. The default network
configure script is @file{/etc/qemu-ifup} and the default network
deconfigure script is @file{/etc/qemu-ifdown}. Use @option{script=no}
or @option{downscript=no} to disable script execution. Example:
@example
qemu linux.img -net nic -net tap
@end example
More complicated example (two NICs, each one connected to a TAP device)
@example
qemu linux.img -net nic,vlan=0 -net tap,vlan=0,ifname=tap0 \
-net nic,vlan=1 -net tap,vlan=1,ifname=tap1
@end example
@item -net socket[,vlan=@var{n}][,name=@var{name}][,fd=@var{h}][,listen=[@var{host}]:@var{port}][,connect=@var{host}:@var{port}]
Connect the VLAN @var{n} to a remote VLAN in another QEMU virtual
machine using a TCP socket connection. If @option{listen} is
specified, QEMU waits for incoming connections on @var{port}
(@var{host} is optional). @option{connect} is used to connect to
another QEMU instance using the @option{listen} option. @option{fd}=@var{h}
specifies an already opened TCP socket.
Example:
@example
# launch a first QEMU instance
qemu linux.img -net nic,macaddr=52:54:00:12:34:56 \
-net socket,listen=:1234
# connect the VLAN 0 of this instance to the VLAN 0
# of the first instance
qemu linux.img -net nic,macaddr=52:54:00:12:34:57 \
-net socket,connect=127.0.0.1:1234
@end example
@item -net socket[,vlan=@var{n}][,name=@var{name}][,fd=@var{h}][,mcast=@var{maddr}:@var{port}]
Create a VLAN @var{n} shared with another QEMU virtual
machines using a UDP multicast socket, effectively making a bus for
every QEMU with same multicast address @var{maddr} and @var{port}.
NOTES:
@enumerate
@item
Several QEMU can be running on different hosts and share same bus (assuming
correct multicast setup for these hosts).
@item
mcast support is compatible with User Mode Linux (argument @option{eth@var{N}=mcast}), see
@url{http://user-mode-linux.sf.net}.
@item
Use @option{fd=h} to specify an already opened UDP multicast socket.
@end enumerate
Example:
@example
# launch one QEMU instance
qemu linux.img -net nic,macaddr=52:54:00:12:34:56 \
-net socket,mcast=230.0.0.1:1234
# launch another QEMU instance on same "bus"
qemu linux.img -net nic,macaddr=52:54:00:12:34:57 \
-net socket,mcast=230.0.0.1:1234
# launch yet another QEMU instance on same "bus"
qemu linux.img -net nic,macaddr=52:54:00:12:34:58 \
-net socket,mcast=230.0.0.1:1234
@end example
Example (User Mode Linux compat.):
@example
# launch QEMU instance (note mcast address selected
# is UML's default)
qemu linux.img -net nic,macaddr=52:54:00:12:34:56 \
-net socket,mcast=239.192.168.1:1102
# launch UML
/path/to/linux ubd0=/path/to/root_fs eth0=mcast
@end example
@item -net vde[,vlan=@var{n}][,name=@var{name}][,sock=@var{socketpath}][,port=@var{n}][,group=@var{groupname}][,mode=@var{octalmode}]
Connect VLAN @var{n} to PORT @var{n} of a vde switch running on host and
listening for incoming connections on @var{socketpath}. Use GROUP @var{groupname}
and MODE @var{octalmode} to change default ownership and permissions for
communication port. This option is available only if QEMU has been compiled
with vde support enabled.
Example:
@example
# launch vde switch
vde_switch -F -sock /tmp/myswitch
# launch QEMU instance
qemu linux.img -net nic -net vde,sock=/tmp/myswitch
@end example
@item -net none
Indicate that no network devices should be configured. It is used to
override the default configuration (@option{-net nic -net user}) which
is activated if no @option{-net} options are provided.
@item -tftp @var{dir}
When using the user mode network stack, activate a built-in TFTP
server. The files in @var{dir} will be exposed as the root of a TFTP server.
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 -bootp @var{file}
When using the user mode network stack, broadcast @var{file} as the BOOTP
filename. In conjunction with @option{-tftp}, this can be used to network boot
a guest from a local directory.
Example (using pxelinux):
@example
qemu -hda linux.img -boot n -tftp /path/to/tftp/files -bootp /pxelinux.0
@end example
@item -smb @var{dir}
When using the user mode network stack, activate a built-in SMB
server so that Windows OSes can access to the host files in @file{@var{dir}}
transparently.
In the guest Windows OS, the line:
@example
10.0.2.4 smbserver
@end example
must be added in the file @file{C:\WINDOWS\LMHOSTS} (for windows 9x/Me)
or @file{C:\WINNT\SYSTEM32\DRIVERS\ETC\LMHOSTS} (Windows NT/2000).
Then @file{@var{dir}} can be accessed in @file{\\smbserver\qemu}.
Note that a SAMBA server must be installed on the host OS in
@file{/usr/sbin/smbd}. QEMU was tested successfully with smbd version
2.2.7a from the Red Hat 9 and version 3.0.10-1.fc3 from Fedora Core 3.
@item -redir [tcp|udp]:@var{host-port}:[@var{guest-host}]:@var{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.
@end table
Bluetooth(R) options:
@table @option
@item -bt hci[...]
Defines the function of the corresponding Bluetooth HCI. -bt options
are matched with the HCIs present in the chosen machine type. For
example when emulating a machine with only one HCI built into it, only
the first @code{-bt hci[...]} option is valid and defines the HCI's
logic. The Transport Layer is decided by the machine type. Currently
the machines @code{n800} and @code{n810} have one HCI and all other
machines have none.
@anchor{bt-hcis}
The following three types are recognized:
@table @code
@item -bt hci,null
(default) The corresponding Bluetooth HCI assumes no internal logic
and will not respond to any HCI commands or emit events.
@item -bt hci,host[:@var{id}]
(@code{bluez} only) The corresponding HCI passes commands / events
to / from the physical HCI identified by the name @var{id} (default:
@code{hci0}) on the computer running QEMU. Only available on @code{bluez}
capable systems like Linux.
@item -bt hci[,vlan=@var{n}]
Add a virtual, standard HCI that will participate in the Bluetooth
scatternet @var{n} (default @code{0}). Similarly to @option{-net}
VLANs, devices inside a bluetooth network @var{n} can only communicate
with other devices in the same network (scatternet).
@end table
@item -bt vhci[,vlan=@var{n}]
(Linux-host only) Create a HCI in scatternet @var{n} (default 0) attached
to the host bluetooth stack instead of to the emulated target. This
allows the host and target machines to participate in a common scatternet
and communicate. Requires the Linux @code{vhci} driver installed. Can
be used as following:
@example
qemu [...OPTIONS...] -bt hci,vlan=5 -bt vhci,vlan=5
@end example
@item -bt device:@var{dev}[,vlan=@var{n}]
Emulate a bluetooth device @var{dev} and place it in network @var{n}
(default @code{0}). QEMU can only emulate one type of bluetooth devices
currently:
@table @code
@item keyboard
Virtual wireless keyboard implementing the HIDP bluetooth profile.
@end table
@end table
i386 target only:
@table @option
@item -win2k-hack
Use it when installing Windows 2000 to avoid a disk full bug. After
Windows 2000 is installed, you no longer need this option (this option
slows down the IDE transfers).
@item -rtc-td-hack
Use it if you experience time drift problem in Windows with ACPI HAL.
This option will try to figure out how many timer interrupts were not
processed by the Windows guest and will re-inject them.
@item -no-fd-bootchk
Disable boot signature checking for floppy disks in Bochs BIOS. It may
be needed to boot from old floppy disks.
@item -no-acpi
Disable ACPI (Advanced Configuration and Power Interface) support. Use
it if your guest OS complains about ACPI problems (PC target machine
only).
@item -no-hpet
Disable HPET support.
@item -acpitable [sig=@var{str}][,rev=@var{n}][,oem_id=@var{str}][,oem_table_id=@var{str}][,oem_rev=@var{n}] [,asl_compiler_id=@var{str}][,asl_compiler_rev=@var{n}][,data=@var{file1}[:@var{file2}]...]
Add ACPI table with specified header fields and context from specified files.
@end table
Linux boot specific: When using these options, you can use a given
Linux kernel without installing it in the disk image. It can be useful
for easier testing of various kernels.
@table @option
@item -kernel @var{bzImage}
Use @var{bzImage} as kernel image.
@item -append @var{cmdline}
Use @var{cmdline} as kernel command line
@item -initrd @var{file}
Use @var{file} as initial ram disk.
@end table
Debug/Expert options:
@table @option
@item -serial @var{dev}
Redirect the virtual serial port to host character device
@var{dev}. 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 serial
ports.
Use @code{-serial none} to disable all serial ports.
Available character devices are:
@table @code
@item vc[:WxH]
Virtual console. Optionally, a width and height can be given in pixel with
@example
vc:800x600
@end example
It is also possible to specify width or height in characters:
@example
vc:80Cx24C
@end example
@item pty
[Linux only] Pseudo TTY (a new PTY is automatically allocated)
@item none
No device is allocated.
@item null
void device
@item /dev/XXX
[Linux only] Use host tty, e.g. @file{/dev/ttyS0}. The host serial port
parameters are set according to the emulated ones.
@item /dev/parport@var{N}
[Linux only, parallel port only] Use host parallel port
@var{N}. Currently SPP and EPP parallel port features can be used.
@item file:@var{filename}
Write output to @var{filename}. No character can be read.
@item stdio
[Unix only] standard input/output
@item pipe:@var{filename}
name pipe @var{filename}
@item COM@var{n}
[Windows only] Use host serial port @var{n}
@item udp:[@var{remote_host}]:@var{remote_port}[@@[@var{src_ip}]:@var{src_port}]
This implements UDP Net Console.
When @var{remote_host} or @var{src_ip} are not specified
they default to @code{0.0.0.0}.
When not using a specified @var{src_port} a random port is automatically chosen.
@item msmouse
Three button serial mouse. Configure the guest to use Microsoft protocol.
If you just want a simple readonly console you can use @code{netcat} or
@code{nc}, by starting qemu with: @code{-serial udp::4555} and nc as:
@code{nc -u -l -p 4555}. Any time qemu writes something to that port it
will appear in the netconsole session.
If you plan to send characters back via netconsole or you want to stop
and start qemu a lot of times, you should have qemu use the same
source port each time by using something like @code{-serial
udp::4555@@:4556} to qemu. Another approach is to use a patched
version of netcat which can listen to a TCP port and send and receive
characters via udp. If you have a patched version of netcat which
activates telnet remote echo and single char transfer, then you can
use the following options to step up a netcat redirector to allow
telnet on port 5555 to access the qemu port.
@table @code
@item Qemu Options:
-serial udp::4555@@:4556
@item netcat options:
-u -P 4555 -L 0.0.0.0:4556 -t -p 5555 -I -T
@item telnet options:
localhost 5555
@end table
@item tcp:[@var{host}]:@var{port}[,@var{server}][,nowait][,nodelay]
The TCP Net Console has two modes of operation. It can send the serial
I/O to a location or wait for a connection from a location. By default
the TCP Net Console is sent to @var{host} at the @var{port}. If you use
the @var{server} option QEMU will wait for a client socket application
to connect to the port before continuing, unless the @code{nowait}
option was specified. The @code{nodelay} option disables the Nagle buffering
algorithm. If @var{host} is omitted, 0.0.0.0 is assumed. Only
one TCP connection at a time is accepted. You can use @code{telnet} to
connect to the corresponding character device.
@table @code
@item Example to send tcp console to 192.168.0.2 port 4444
-serial tcp:192.168.0.2:4444
@item Example to listen and wait on port 4444 for connection
-serial tcp::4444,server
@item Example to not wait and listen on ip 192.168.0.100 port 4444
-serial tcp:192.168.0.100:4444,server,nowait
@end table
@item telnet:@var{host}:@var{port}[,server][,nowait][,nodelay]
The telnet protocol is used instead of raw tcp sockets. The options
work the same as if you had specified @code{-serial tcp}. The
difference is that the port acts like a telnet server or client using
telnet option negotiation. This will also allow you to send the
MAGIC_SYSRQ sequence if you use a telnet that supports sending the break
sequence. Typically in unix telnet you do it with Control-] and then
type "send break" followed by pressing the enter key.
@item unix:@var{path}[,server][,nowait]
A unix domain socket is used instead of a tcp socket. The option works the
same as if you had specified @code{-serial tcp} except the unix domain socket
@var{path} is used for connections.
@item mon:@var{dev_string}
This is a special option to allow the monitor to be multiplexed onto
another serial port. The monitor is accessed with key sequence of
@key{Control-a} and then pressing @key{c}. See monitor access
@ref{pcsys_keys} in the -nographic section for more keys.
@var{dev_string} should be any one of the serial devices specified
above. An example to multiplex the monitor onto a telnet server
listening on port 4444 would be:
@table @code
@item -serial mon:telnet::4444,server,nowait
@end table
@item braille
Braille device. This will use BrlAPI to display the braille output on a real
or fake device.
@end table
@item -parallel @var{dev}
Redirect the virtual parallel port to host device @var{dev} (same
devices as the serial port). On Linux hosts, @file{/dev/parportN} can
be used to use hardware devices connected on the corresponding host
parallel port.
This option can be used several times to simulate up to 3 parallel
ports.
Use @code{-parallel none} to disable all parallel ports.
@item -monitor @var{dev}
Redirect the monitor to host device @var{dev} (same devices as the
serial port).
The default device is @code{vc} in graphical mode and @code{stdio} in
non graphical mode.
@item -pidfile @var{file}
Store the QEMU process PID in @var{file}. It is useful if you launch QEMU
from a script.
@item -S
Do not start CPU at startup (you must type 'c' in the monitor).
@item -s
Wait gdb connection to port 1234 (@pxref{gdb_usage}).
@item -p @var{port}
Change gdb connection port. @var{port} can be either a decimal number
to specify a TCP port, or a host device (same devices as the serial port).
@item -d
Output log in /tmp/qemu.log
@item -hdachs @var{c},@var{h},@var{s},[,@var{t}]
Force hard disk 0 physical geometry (1 <= @var{c} <= 16383, 1 <=
@var{h} <= 16, 1 <= @var{s} <= 63) and optionally force the BIOS
translation mode (@var{t}=none, lba or auto). Usually QEMU can guess
all those parameters. This option is useful for old MS-DOS disk
images.
@item -L @var{path}
Set the directory for the BIOS, VGA BIOS and keymaps.
@item -bios @var{file}
Set the filename for the BIOS.
@item -kernel-kqemu
Enable KQEMU full virtualization (default is user mode only).
@item -no-kqemu
Disable KQEMU kernel module usage. KQEMU options are only available if
KQEMU support is enabled when compiling.
@item -enable-kvm
Enable KVM full virtualization support. This option is only available
if KVM support is enabled when compiling.
@item -no-reboot
Exit instead of rebooting.
@item -no-shutdown
Don't exit QEMU on guest shutdown, but instead only stop the emulation.
This allows for instance switching to monitor to commit changes to the
disk image.
@item -loadvm @var{file}
Start right away with a saved state (@code{loadvm} in monitor)
@item -daemonize
Daemonize the QEMU process after initialization. QEMU will not detach from
standard IO until it is ready to receive connections on any of its devices.
This option is a useful way for external programs to launch QEMU without having
to cope with initialization race conditions.
@item -option-rom @var{file}
Load the contents of @var{file} as an option ROM.
This option is useful to load things like EtherBoot.
@item -clock @var{method}
Force the use of the given methods for timer alarm. To see what timers
are available use -clock ?.
@item -localtime
Set the real time clock to local time (the default is to UTC
time). This option is needed to have correct date in MS-DOS or
Windows.
@item -startdate @var{date}
Set the initial date of the real time clock. Valid formats for
@var{date} are: @code{now} or @code{2006-06-17T16:01:21} or
@code{2006-06-17}. The default value is @code{now}.
@item -icount [N|auto]
Enable virtual instruction counter. The virtual cpu will execute one
instruction every 2^N ns of virtual time. If @code{auto} is specified
then the virtual cpu speed will be automatically adjusted to keep virtual
time within a few seconds of real time.
Note that while this option can give deterministic behavior, it does not
provide cycle accurate emulation. Modern CPUs contain superscalar out of
order cores with complex cache hierarchies. The number of instructions
executed often has little or no correlation with actual performance.
@item -echr numeric_ascii_value
Change the escape character used for switching to the monitor when using
monitor and serial sharing. The default is @code{0x01} when using the
@code{-nographic} option. @code{0x01} is equal to pressing
@code{Control-a}. You can select a different character from the ascii
control keys where 1 through 26 map to Control-a through Control-z. For
instance you could use the either of the following to change the escape
character to Control-t.
@table @code
@item -echr 0x14
@item -echr 20
@end table
@item -chroot dir
Immediately before starting guest execution, chroot to the specified
directory. Especially useful in combination with -runas.
@item -runas user
Immediately before starting guest execution, drop root privileges, switching
to the specified user.
