[Q] Is there a way to set ro.kernel.qemu to 0 in emulator? topic

I have tried:
1. add 'ro.kernel.qemu=0' in default.prop in ramdisk.img
2. add 'setprop ro.kernel.qemu 0' in init.goldfish.rc in ramdisk.img

But all these did not work. When I start the emulator with modified ramdisk.img, ro.kernel.qemu is 1 in the output of 'adb shell getprop'.

I am now trying to rebuild the kernel to set it to 0, but I did not find where ro.kernel.qemu is set in the kernel source code.

Appreciated for any advices.
