Re: [Qemu-discuss] qemu 1.3.0 hangs on macos 10.8.2

[cmason]

I tried this again under the debugger.  

I configured qemu like this:

./configure --disable-sdl --disable-kvm --enable-cocoa --cc=gcc-4.2
--host-cc=gcc-4.2 --enable-debug   --extra-cflags=-g  
--extra-ldflags=-g

And ran it like this:

qemu-system-arm -nographic -M versatilepb -kernel
vmlinuz-2.6.32-5-versatile -initrd initrd.img-2.6.32-5-versatile -hda
debian_squeeze_armel_standard.qcow2 -append "root=/dev/sda1
console=ttyAMA0"

With images, kernel, and initrd described here:

http://psellos.com/2012/08/2012.08.qemu-arm-osx.html

And I get:
