qemu-arm仿真工具，在Ubuntu中的安装方法：sudo apt-get install qemu。
使用QEMU仿真ARM  Linux系统
使用方法，网上有很多文章可以参考：

创建一个虚拟硬盘$ qemu-img create -f qcow hda.img 10G


创建文件系统   sudo dd if=/dev/zero of=rootfs.img bs=1M count=100
   sudo mkfs.ext2 -N 512 rootfs.img

安装Linux系统$ qemu-system-arm -M versatilepb -kernel vmlinuz-2.6.18-6-versatile -initrd initrd.gz -hda hda.img -append "root=/dev/ram"

运行Linux系统$ qemu-system-arm -M versatilepb -kernel vmlinuz-2.6.18-6-versatile -initrd initrd.img-2.6.18-6-versatile -hda hda.img -append "root=/dev/sda1"


qemu-system-arm -kernel zImage.integrator -initrd arm_root.img -nographic -append "console=ttyAMA0"


qemu-system-arm -kernel <path to the kernel image>/zImage-<kernel version>-qemu-arm -initrd ususe.img -nographic -append console=ttyAMA0

Framebuffer console:

qemu-system-arm -kernel <path to the kernel image>/zImage-<kernel version>-qemu-arm -initrd ususe.img -append console=tty1


转载示例先安装Qemu,因为sdl很难搞定.linux建议下载qemu-0.8.2-i386.tar.gz,在根目录下解压即可,自动安装到bin.
创建模拟盘
sudo qemu-img create -f qcow hda.img 1G
下载kernel
sudo wget http://people.debian.org/~aurel32/arm-versatile/vmlinuz-2.6.18-2-versatile

sudo wget http://people.debian.org/~aurel32/arm-versatile/initrd.img-2.6.18-2-versatile
下载initrd安装文件
sudo wget http://ftp.nl.debian.org/debian/dists/testing/main/installer-arm/rc1/images/rpc/netboot/initrd.gz
安装Debian Etch(在桌面环境下)
sudo qemu-system-arm -M versatilepb -kernel vmlinuz-2.6.18-2-versatile -initrd initrd.gz -hda hda.img -append "root=/dev/ram"
跳过安装
运行(在桌面环境下)
sudo qemu-system-arm -M versatilepb -kernel vmlinuz-2.6.18-2-versatile -initrd initrd.img-2.6.18-2-versatile -hda hda.img -append "root=/dev/sda1"
出现login之后退出
安装相应的内核
sudo apt-get install initramfs-tools
sudo  wget http://people.debian.org/~aurel32/arm-versatile/linux-image-2.6.18-2-versatile_2.6.18-5+versatile_arm.deb
sudo  dpkg -i linux-image-2.6.18-2-versatile_2.6.18-5+versatile_arm.deb
然后重新运行qemu
进入命令行,输入dmeg出现 arm的提示就ok




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.
