Also i found the emulator can be lunched successfuly when i set kernel argument as the prebuilts one. i.e. emulator -verbose -debug all -system ${OUT}/system.img -kernel /home/ju/Workspace/mirror/prebuilts/qemu-kernel/x86/kernel-qemu -ramdisk ${OUT}/ramdisk.img -data ${OUT}/userdata-qemu.img -cache ${OUT}/cache.img So i am wonding if this error is about the goldfish? Please help. Thanks.

FYI: Had several issue getting this to work on the device a25x86, but if we do not specify any device, then it picks up the config from build.avd in $OUT. That seems to be working fine!
