'disk_image' is a raw hard image image for IDE hard disk 0

Standard options:
-M machine   select emulated machine (-M ? for list)
-fda/-fdb file use->file' as floppy disk 0/1 image
-hda/-hdb file use->file' as IDE hard disk 0/1 image
-hdc/-hdd file use->file' as IDE hard disk 2/3 image
-cdrom file   use->file' as IDE cdrom image (cdrom is ide1 master)
-boot [a|c|d|n] boot on floppy (a), hard disk (c), CD-ROM (d), or network (n)
-snapshot    write to temporary files instead of disk image files
-no-quit    disable SDL window close capability
-no-fd-bootchk disable boot signature checking for floppy disks
-m megs     set virtual RAM size to megs MB [default=128]
-smp n     set the number of CPUs to->n' [default=1]
-nographic   disable graphical output and redirect serial I/Os to console
-audio-help   print list of audio drivers and their options
-soundhw c1,... enable audio support
        and only specified sound cards (comma separated list)
        use -soundhw ? to get the list of supported cards
        use -soundhw all to enable all of them
-localtime   set the real time clock to local time [default=utc]
-full-screen  start in full screen
-win2k-hack   use it when installing Windows 2000 to avoid a disk full bug
-usb      enable the USB driver (will be the default soon)
-usbdevice name add the host or guest USB device->name'

Network options:
-net nic[,vlan=n][,macaddr=addr][,model=type]
        create a new Network Interface Card and connect it to VLAN->n'
-net user[,vlan=n][,hostname=host]
        connect the user mode network stack to VLAN->n' and send
        hostname->host' to DHCP clients
-net tap[,vlan=n],ifname=name
        connect the host TAP network interface to VLAN->n'
-net socket[,vlan=n][,fd=h][,listen=[host]:port][,connect=host:port]
        connect the vlan->n' to another VLAN using a socket connection
-net socket[,vlan=n][,fd=h][,mcast=maddr:port]
        connect the vlan->n' to multicast maddr and port
-net none    use it alone to have zero network devices; if no -net option
        is provided, the default is->-net nic -net user'

-tftp prefix  allow tftp access to files starting with prefix [-net user]
-redir [tcp|udp]:host-port:[guest-host]:guest-port
        redirect TCP or UDP connections from host to guest [-net user]

Linux boot specific:
-kernel bzImage use->bzImage' as kernel image
-append cmdline use->cmdline' as kernel command line
-initrd file  use->file' as initial ram disk

Debug/Expert options:
-monitor dev  redirect the monitor to char device->dev'
-serial dev   redirect the serial port to char device->dev'
-parallel dev  redirect the parallel port to char device->dev'
-pidfile file  Write PID to->file'
-S       freeze CPU at startup (use->c' to start execution)
-s       wait gdb connection to port 1234
-p port     change gdb connection port
-d item1,...  output log to /tmp/qemu.log (use -d ? for a list of log items)
-hdachs c,h,s[,t] force hard disk 0 physical geometry and the optional BIOS
        translation (t=none or lba) (usually qemu can guess them)
-L path     set the directory for the BIOS, VGA BIOS and keymaps
-kernel-kqemu  enable KQEMU full virtualization (default is user mode only)
-no-kqemu    disable KQEMU kernel module usage
-std-vga    simulate a standard VGA card with VESA Bochs Extensions
        (default is CL-GD5446 PCI VGA)
-no-acpi    disable ACPI
-no-reboot   exit instead of rebooting
-loadvm file  start right away with a saved state (loadvm in monitor)
-vnc display  start a VNC server on display
-option-rom rom load a file, rom, into the option ROM space

During emulation, the following keys are useful:
ctrl-alt-f   toggle full screen
ctrl-alt-n   switch to virtual console->n'
ctrl-alt    toggle mouse and keyboard grab

When using -nographic, press->ctrl-a h' to get some help.
