To set up an emulated environment of the Raspberry Pi software on OSX one will need:
A Cross-Compiling Tool for the CPU architecture of RPi. ( eg. ARM
EABI Toolchain )
The RPi Kernel.
The RPi root filesystem.
The Emulator (QEMU).
The Cross-Compiling Tool for the ARM architecture.
Assuming one already have the latest Xcode and command line tools from Apple ...
Here is a link for that file I have uploaded it to dropbox.
Also, it's been made available on github. Link --> https://github.com/dhruvvyas90/qemu-rpi-kernel
Ok, so I figured it out:
I needed to comment out one line in /etc/ld.so.preload file by adding # at the line beginning before starting Raspbian (problems with booting disappeared) and use:
qemu-system-armw.exe -M versatilepb -m 256 -cpu arm1176 -no-reboot -serial stdio -kernel kernel-qemu -hda rpi_disk.vmdk -append "root=/dev/sda2 panic=1"
command to ...
This is an old question, but:
You won't be able to use KVM to run an x86 guest on the Raspberry Pi (any version), as the Raspberry Pi uses an ARM CPU core. Now, this doesn't mean that you can't run an x86 guest at all, but performance will be quite slow. (The link above is likely about using KVM to run an ARM guest, not an x86 guest).
Before the KVM ...
As @dastaan said, the kernel version needs to match the img file. I was trying to use a 4.1 kernel version image file with a 3.18 kernel.
Now that I am using the proper image, it works.
Edit: Getting this to work is pretty straightforward: Grab the image from https://github.com/dhruvvyas90/qemu-rpi-kernel/, then download the corresponding Raspian ...
The error message makes clear that Minecraft can't find the
Pi GPU since it's not there. I'm pretty sure there is no way
around that requirement either.
If you are looking to use the Pi edition Python API, plugins
for Desktop Minecraft exist to emulate this API :
This works for me on MacOS Mojave,
Create a file called qemu_script.sh and copy-paste the code below
give execution perms and execute,
$ chmod +x qemu_script.sh
brew install qemu
export QEMU=$(which qemu-system-arm)
If you were looking to go mobile, SSH or VNC are the best options for working without a separate monitor. Both of these require the Mac and the Pi to be connected to the same WIFI/Ethernet network, however I have read somewhere you can directly attach them with an Ethernet cable. Something worth looking up.
SSH is the best option if you are only using the ...
QEMU does not emulate the Videocore hardware; programs that try to interface with it through VCHIQ will fail. It looks like this QEMU fork might get you closer to proper emulation, but I wouldn't get my hopes up.
When booting first time you should use bash as init application and change /etc/ld.so.preload. Please note -append parameter:
qemu-system-arm -kernel kernel-qemu -cpu arm1176 -m 256 -M versatilepb -no-reboot -serial stdio -append "root=/dev/sda2 panic=1 rootfstype=ext4 rw init=/bin/bash console=ttyAMA0,115200" -hda 2014-12-24-wheezy-raspbian.img

There is a ready to run paid option that runs over QEMU: https://snorfi.us/raspiemu/
If you don't want to pay for it you can also download the alpha version in https://sourceforge.net/projects/raspberrypiemulator/
The append line adds extra options to the kernel command line in UNIX derivatives. You can add many extra options such as
root device (/dev/sda2 in your example)
debugging options such as 'quiet'
hdd emaulation (ide-scsi)
boot type (single, rescue etc.)
You can find which options you can pass to append line in QEMU kernel options ...
While brought up your guest OS, If you didn't specify any nic interface, by default QEMU will create one and assign the IP 10.0.2.15. but it will not have any connectivity. so guest OS will not able to ping host OS.
(For more details about QEMU networking refer http://wiki.qemu.org/Documentation/Networking).
Better way I would suggest is bridge->tap ...
You are still using "versatilepb". If you want to emulate a Raspberry Pi, use "raspi"
The precompiled DTB files can be downloaded from the foundation firmware github.

I know this is an old question but since it comes up in Google searches and I was looking for the same information, I'll post what I've found.
There's a solution for Linux based qemu here and there's Windows based information here.
Can qemu give USB interface for guest?
Yes, QEMU can pass USB devices to a guest. See this document.
Is raspberry pi performance suitable for the task?
No, the Rasperry Pi has a very limited processor. Instead of virtualizing another Linux guest, consider directly installing CUPS.
Try installing qemu version 1.7.1 (the version prior to 2.0.0).
I had very similar problems with qemu 2.0.0 (installed via macports in my case), and switching back to the prior version made everything work.
I do not use homebrew, but this response at Stackoverflow has detailed instructions to revert to an earlier version of any package using Homebrew.
How did you resize your image?
I resized as follows, it works fine for me. (I'm on Ubuntu 12.04 and trying with raspbian):
root@unknown:~# qemu-img info 2014-09-09-wheezy-raspbian.img
file format: raw
virtual size: 3.1G (3276800000 bytes)
disk size: 3.1G

I had similar issues and I finally got this working last night, on OS X 10.8.5 with QEMU v2.2.0, after working on/off for two weeks.
I was prompted by the question, Can I program for Arduino without having a real board?, to try to use a real emulator, such as QEMU, as suggested by zmo, in a comment to Anindo Ghosh's answer.
I thought that I would ...
I had the exact same issue using bash as init. This will get you access to the system, but as you've seen login and some other stuff won't work.
Per the instructions at http://xecdesign.com/qemu-emulating-raspberry-pi-the-easy-way/ you need to comment out a line in /etc/ld.so.preload.
After this a normal boot without a custom init will work mostly (I have ...
Defining what a decent speed is is not possible. Perhaps for the type of development and for the need when testing the developed software, a qemu VM is perfect for you. Just try it and see for yourself if the time it takes is acceptable or not.
Then depending on the type of development you want to do, portability might be an issue or not. What is your ...
Adobe flash is proprietary software, and there is no version compiled for ARMv6. Since it is not open source, that is the end of that. Running an x86 version through Wine or QEMU, to the extent that it is even possible, will be dreadful.
There is an open source .swf player, gnash, which is in Raspbian and even looks to use openGL bindings, meaning it ...
seam be this is wrong: root=/dev/sda2
Try replace by (waitroot will give time to read the error):
-append "root=/dev/sda2 waitroot rootfstype=ext4 rw init=/bin/bash"
-append "root=/dev/vda2 waitroot rootfstype=ext4 rw init=/bin/bash"
-append "root=/dev/hda2 waitroot rootfstype=ext4 rw init=/bin/bash"

You can run qemu-system (without KVM !) inside Virtualbox - this works fine across architectures.
The real problem is that the board emulation
"Versatile" can not run "Raspbery Pi" operating systems properly.
Build QEMU from source , it supports the "Raspberry Pi" board.
Older versions of QEMU did not emulate the Raspberry Pi but a "Versatile PB" board.
Therefore a custom "Versatile" kernel is running inside QEMU , the userland of Raspberry Pi images works somewhat fine on top of it (YMMV) - as the whole point of the Linux kernel is to provide this very abstraction.
See here on how to really emulate the Raspberry Pi 2 with ...
I succeeded in launching Raspbian Jessie Lite on Kubuntu 14.04 after I compiled QEMU from git. There's a bit of a problem though: I haven't made the keyboard input work (have to use virtual serial terminal instead).
Anyway, here's what I did:
1) Compile QEMU from git (adjust configure options for your needs, but these did work well enough for me):
$ sudo ...
Can I expect the controller to run at full USB 2.0 and 100 ethernet speed at the same time?
No, the total bus speed of everything combined is limited to 280 Mbps. This is in theory enough if you are passing 40 Mbps through from USB to ethernet.
It has a Realtek RTL8812AU chipset.
This one isn't explicitly referenced in the vanilla kernel source driver ...
If you don't set the -net parameter (or set it to -net nic -net user) the guest machine will get the user mode network which supports TCP and UDP (not ICMP so no ping). This should be enough for some basic usage.
