After installing QEMU, and libvirt the ARM root file system and an xml file that contains instructions on how to install the fedora arm operating system. There was an issue involving SELinux, in order to solve this we had to HonkKong to permissive mode. After this point The virtual machine was able to boot.

The ARM virtual machines are not a viable solution for our Fedora-Arm Koji Farm. The additional compilation times from the virtual machines can amount to ten times slower than that of the OpenRD client, which can really come into affect when compiling large packages which is not acceptable. The OpenRD clients were inexpensive and almost three OpenRD clients can be purchased at the cost of one of the existing machines. Another solution would be a SheevaPlug, which is generally cheaper than the OpenRD client. The SheevaPlug hardware is identical to the OpenRD, so similar performance should be expected. The SheevaPlug, however has less ports such as video or sata. Though, the OpenRD client out performs the virtual machines they do have a practical use. If an individual or organization could not afford to buy additional hardware and wishes to develop applications or is required to support them and performance is not an issue, virtualization for ARM would be a viable solution.
