我在 x86 系统上安装了 qemu-0.13.0。我从以下网址下载了 debian-powerpc 映像http://people.debian.org/~aurel32/qemu/powerpc/并使用这个命令
$qemu-system-ppc -hda debian_lenny_powerpc_small.qcow2 -nographic
这是客户操作系统 (debian-507-powerpc (2.6.26-1-powerpc) ) 的 cpuinfo
processor : 0
cpu : 740/750
temperature : 62-64 C (uncalibrated)

之后，我在该客户操作系统上安装了 qemu-0.13.0，并尝试在其上运行相同的 debian-powerpc 映像。
$qemu-system-ppc -hda debian_lenny_powerpc_small.qcow2 -nographic
启动过程卡住了：

returning from prom_init
谢谢，

当您使用 -nographic 时，您无法看到启动进度。
从“从prom_init返回”到“Debian GNU/Linux 6.0 debian-powerpc ttyPZ0”通常需要很长时间。
