如下是qemu-system-arm的帮助文件:QEMU PC emulator version 0.9.0, Copyright (c) 2003-2007 Fabrice Bellard
usage: qemu [options] [disk_image]
'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
-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
-k language use keyboard layout (for example "fr" for French)
-localtime set the real time clock to local time [default=utc]
-full-screen start in full screen
-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][,fd=h][,ifname=name][,script=file]
connect the host TAP network interface to VLAN 'n' and use
the network script 'file' (default=/etc/qemu-ifup);
use 'script=no' to disable script execution;
use 'fd=h' to connect to an already opened TAP interface
-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]
-smb dir allow SMB access to files in 'dir' [-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
-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
-daemonize daemonize QEMU after initializing
-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.
