Using Pidora in a QEMU environment has some important restrictions to note. The plan model that is used to allow emulate Pidora QEMU to compose new Pidora imageshas a hard coded restriction on how much RAM it can use (256 MB). This could increase speed The programs we use (livemedia-creator) for making composing new composesimages require much more RAM, add which makes the Pidora QEMU Environment a standard operating procedure for completing it, bad place to try and finally allow other users to make remixes using the Pidora 2014 package setcreate images.(See compose on Fedora Arm QEMU)

This tutorial is basically just using the tutorial found on this site(http://xecdesign.com/compiling<pre>yum install qemu-system-qemuarm</), with some added steps specifically for pidora.pre>

=== Manual Compile ===If the above package does not allow you to boot Pidora through QEMU, you can try the manual instructions below. This setup is done completely on fedora 20. If will allow you are using ubuntu/debian it might be easier to use the site aboveQEMU software without actually installing it on your system (I don't like installing source files that are not managed by yum).

This setup avoids The manual compile will require the installation dependencies for the program to already be installed. Below is a list of packages that might be required (I think only the newly compiled qemu, so that your system stays clean, and keeps your system and any already devel ones are needed?).<pre># Install Dependencies (not sure if the non-devel packages are required?)yum install qemu instances managed by yum.gcc-++ zlib zlib-devel SDL SDL-devel pixman pixman-devel libfdt-devel libtool glib2 glib2-devel</pre>

<pre># use whatever Choose the directory you'd likefor the compiled QEMU software

# 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

# Put == Boot with SSH Enabled ==There is a # option you can specify in front of the first line so boot command that it looks like will allow a port to be forwarded from a localhost to the port on the pidora machine. For example, to connect to the raspberry pi qemu environment with ssh you would add thisline:#/usr/lib/arm<pre>-linux-gnueabihfredir tcp:2222::22</libcofi_rpi.sopre>

Press ctrl-x then y then enter This will redirect all traffic from localhost on your main machine through the port 2222 to save and exit.(Optional) Use steps 2 to 4 above to create a file /etc/udev/rules.d/90-the raspberry pi qemumachine port 22.rules with Make sure ssh is running on the following contentqemu machine:KERNEL=="sda", SYMLINK+="mmcblk0"<pre>KERNEL=="sda?", SYMLINK+="mmcblk0p%n"systemctl enable sshd # To make sshd start at boot timeKERNEL=="sda2", SYMLINK+="root"systemctl start sshd # To start sshd</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>

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