# QEMU (guest) - raspberry pi emulation
#   @FIXME
#   for some reason it drops out of the startup procedure
#   and dumps you to the terminal prematurely
exit
#   if this is not first-run, we are done..
#   else we are ushered into raspi-config (first run only)
#   select "Finish" when done configuring

# OSX terminal (host)
ssh -p 5022 pi@localhost

# If we want to create a Heroku-like atmosphere, we can do
# with Dokku
## Still figuring this part out..

after all working.. can i open .img file and save all files in a SD card, then just input in raspberrypi?

Tested using both kernels and the latest raspbian img (2016-02-09-raspbian-jessie.img).
It closes the emulation window with message: "Kernel panic - not syncing : Attempted to kill init"

Looking in internet people say that is a problem with not compatible kernel, but image and kernel are same version 4.1.

Any tips? @jasonlagaac

Tested those commands:

• qemu-system-arm -kernel kernel-qemu-4.1.13-jessie -cpu arm1176 -m 256 -M versatilepb -no-reboot -serial stdio -append "root=/dev/sda2 panic=1 rootfstype=ext4 rw" -hda 2016-02-09-raspbian-jessie.img
• qemu-system-arm -kernel kernel-qemu-4.1.7-jessie -cpu arm1176 -m 256 -M versatilepb -no-reboot -serial stdio -append "root=/dev/sda2 panic=1 rootfstype=ext4 rw init=/bin/bash" -hda 2016-02-09-raspbian-jessie.img

@mariohmol update image, edit /etc/ld.so.preload and comment line #/usr/lib/arm-linux-gnueabihf/libarmmem.so

I wanna ask how to make the network able to work : (

Hello guys! Check this project out: Raspi Simulator (not mine). If you see in package contents, its all shell scripts in a wrapper.

I wasn't able to get a working init using this process. I had more luck with these instructions, although they are incomplete, and I don't have permission to edit the page. I had to mount the Ubuntu cloud image using qemu-nbd xenial-server-cloudimg-arm64-uefi1.img --connect=/dev/nbd0 and manually add a password for the ubuntu account as shown here, and wait for cloud-init to time out, before I could log into the machine and apt remove cloud-init.
