Fedora 21 Alpha for AArch64
The Alpha release contains all the exciting features of Fedora 21's products in a form that anyone can help test. This testing, guided by the Fedora QA team, helps us target and identify bugs. When these bugs are fixed, we make a Beta release available. A Beta release is code-complete and bears a very strong resemblance to the third and final release. The final release of Fedora 21 is expected in December.
We need your help to make Fedora 21 the best release yet, so please take some time to download and try out the Alpha and make sure the things that are important to you are working. If you find a bug, please report it – every bug you uncover is a chance to improve the experience for millions of Fedora users worldwide. Together, we can make Fedora a rock-solid distribution. We have a culture of coordinating new features and pushing fixes upstream as much as feasible and your feedback will help improve not only Fedora but Linux and free software on the whole. (See the end of this announcement for more information on how to help.)

For the Mustang (Applied Micro X-Gene)
A network installation is the preferred installation method for current Aarch64 hardware targets. In order to begin you will need to setup the installation server, a guide can be found below:
It is possible to start an installation of Fedora 21 Alpha without going through the steps of setting up a PXE server, and rather initiating a network installation through a USB drive formatted appropriately. This may be created using the Fedora 21 Alpha installation media provided, or the following prepared image.
Copy the USB image to an appropriate USB device (minimum 128MB USB stick).
MEDIA= # location of your USB device xzcat Fedora_21_Alpha_Installer.img.xz | sudo dd of=$MEDIA bs=4M
Insert the USB device into the bottom port located at the back of the Mustang board (below the network port), power on the machine and interrupt the boot, choosing the 'shell' option. Once at the EFI shell, enter:
FS0:\EFI\BOOT\BOOTAA64.efi # NOTE - if you recieve an error try - FS1:\EFI\BOOT\BOOTAA64.efi
This will boot the Fedora 21 Alpha installer. When prompted, choose either VNC or Text installation. By default the installer will use the Fedora Master Mirror but you can also use the "Closest Mirror" option for best results.
Reported Bugs and Known Issues
- During installation you may recieve the error "FormatCreateError: ('invalid device specification', '/dev/sda1')".This appears to be intermittent. Restarting the installation will usually work around the error (BZ#1109244).
- At the end of the installation you may receive an error about removing or adding the 'EFI' boot menu entry, if so type 'yes' to continue the installation and once rebooted, interupt the boot process (press any key) add the menu entry as shown below (BZ#1151571):
