= Pidora QEMU =
This tutorial page is basically just using the here to assist people who would like to run Pidora 2014 in a QEMU environment. This tutorial found on has been adapted from this site(website: http://xecdesign.com/compiling-qemu/), with some added steps specifically for pidora.
== Getting The Files ==<pre># use whatever Choose the directory you'd liketo put both the image and the compiled QEMU software
pidora_dir=/data/pidora-qemu
# Make the directory and enter it
mkdir ${pidora_dir}
cd ${pidora_dir}
# Download the QEMU kernel
wget http://xecdesign.com/downloads/linux-qemu/kernel-qemu
# Download the Pidora image
wget http://pidora.ca/pidora/releases/20/images/Pidora-2014-R1.zip
# Unzip the image file
unzip Pidora-2014-R1.zip
</pre>
== Getting QEMU ==
There are multiple ways to get qemu-system-arm. You can compile a new version with a few select flags, or you can try installing the version that your distribution has already compiled. It is possible that the QEMU packaged in your distro was not compiled with the proper flags, however it seems to work on the latest Fedora 20.
=== Package Install ===
This method should probably be good enough to run Pidora in Qemu. I have only tested on Fedora 20, and it works.
<pre>
yum install qemu-system-arm
</pre>
=== Manual Compile ===
If the above package does not allow you to boot Pidora through QEMU, you can try the manual instructions below. This will allow you to use the QEMU software without actually installing it on your system (I don't like installing source files that are not managed by yum).
The manual compile will require the dependencies for the program to already be installed. Below is a list of packages that might be required (I think only the devel ones are needed?).
<pre>
# Install Dependencies (not sure if the non-devel packages are required?)
yum install gcc-++ zlib zlib-devel SDL SDL-devel pixman pixman-devel libfdt-devel libtool glib2 glib2-devel
</pre>
Compile qemu-system-arm:
<pre>
# Choose the directory for the compiled QEMU software
pidora_dir=/data/pidora-qemu
# Make a new directory for QEMU and enter it
mkdir ${pidora_dir}/raspidev/
cd ${pidora_dir/raspidev/
git clone git://git.qemu-project.org/qemu.git
cd ${pidora_dir}/raspidev/qemu/
# Before you can continue, you will probably need to install a bunch of build deps# I will show all Configure the packages I needed to install options for the raspberry pi./configure--target-list="arm-softmmu arm-linux-user" --enable-sdl --prefix=/make to finish successfully# Note: I do NOT make installusr
# I think Finally, compile itmake </pre> = Boot Pidora in QEMU =Make sure you run the steps in "Before Booting" and "The First Boot" before you start Pidora for the first time to avoid issues. == Before Booting =={{Admon/important| Warning! | Running the command "dd" can be dangerous and could result in data loss if not used properly.}}Make sure that you add some more space to the image file. Depending on what you might only want to do with the Pidora image you may want more space. Replace the value in the variable size, with the number of GB to increase the size of the image with.<pre># Choose the directory for the compiled QEMU softwarepidora_dir=/data/pidora-qemu # Size = GBsize=4 dd if=/dev/zero bs=1G count=${size} >> ${pidora_dir}/Pidora-2014-R1.img</pre> == The First Boot ==At this step we need to install boot Pidora, start first boot, and allow it to automatically resize the partition inside the image to the right size. This will only work if you already increase the size of the devel packages image in the below previous steps. <pre># Choose the directory for the compiled QEMU softwarepidora_dir=/data/pidora-qemu # This is the command.to boot the Pidora Image using the compiled version of QEMUyum install gcc${pidora_dir}/raspidev/qemu/arm-++ zlib zlibsoftmmu/qemu-devel SDL SDLsystem-devel pixman pixmanarm -devel libfdtkernel ${pidora_dir}/kernel-devel libtool glib2 glib2qemu -develcpu arm1176 -m 256 -M versatilepb -no-reboot -serial stdio -append "root=/dev/sda2 panic=1 rootfstype=ext4 rw" -hda ${pidora_dir}/Pidora-2014-R1.img</pre> == Pidora Graphical Boot ==Run the commands below. OR
<pre>
#!/bin/bash
# Choose the directory for the compiled QEMU software
pidora_dir=/data/pidora-qemu
# This is the command to boot the Pidora Image using the compiled version of QEMU${pidora_dir}/raspidev/qemu/arm-softmmu/qemu-system-armqemu-system-arm -kernel ${pidora_dir}/kernel-qemu -cpu arm1176 -m 256 -M versatilepb -no-reboot -serial stdio -append "root=/dev/sda2 panic=1 rootfstype=ext4 rw init=/bin/bash3" -hda ${pidora_dir}/Pidora-2014-R1.img</pre>
So you can connect with ssh by running the following command:<pre>ssh -p 2222 root@localhost # Now just close the window or shut it downConnect to raspberry pi qemu over ssh</pre>
=== Multi-User Boot With SSH ===
This is an example of the above multi user boot with the added redirect option to enable ssh.
<pre>
#!/bin/bash
# Choose the directory for the compiled QEMU software
pidora_dir=/data/pidora-qemu

If you don't it might cause some errors when you start first boot and it tries to resize your partitions and filesystem.</pre>

= Issues =
Some issues can occur during the above processes. Some fixes are listed below.
== Manually Resize Pidora ==
{{Admon/important| Warning! | Please make sure you follow all instructions properly, do NOT run fdisk on your main system. fdisk should only be run on the pidora qemu system, otherwise you may break your system.}}
