使用QEMU仿真ARM? Linux系統

使用方法，網上有很多文章可以參考：

創建一個虛擬硬盤

$ qemu-img create -f qcow hda.img 10G

創建文件系統

sudo dd if=/dev/zero of=rootfs.img bs=1M count=100

sudo mkfs.ext2 -N 512 rootfs.img

安裝Linux系統

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

運行Linux系統

$ 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 /zImage--qemu-arm -initrd ususe.img -nographic -append console=ttyAMA0

Framebuffer console:

qemu-system-arm -kernel /zImage--qemu-arm -initrd ususe.img -append console=tty1

轉載示例

先安裝Qemu,因為sdl很難搞定.linux建議下載qemu-0.8.2-i386.tar.gz,在根目錄下解壓即可,自動安裝到bin.

創建模擬盤

sudo qemu-img create -f qcow hda.img 1G

下載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

下載initrd安裝文件

sudo wget http://ftp.nl.debian.org/debian/dists/testing/main/installer-arm/rc1/images/rpc/netboot/initrd.gz

安裝Debian Etch(在桌面環境下)

sudo qemu-system-arm -M versatilepb -kernel vmlinuz-2.6.18-2-versatile -initrd initrd.gz -hda hda.img -append "root=/dev/ram"

跳過安裝

運行(在桌面環境下)

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"

出現login之后退出

安裝相應的內核

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

然后重新運行qemu

進入命令行,輸入dmeg出現 arm的提示就ok

如下是qemu-system-arm的幫助文件：
