Fetching OVMF UEFI from the correct source

1. On the host device, execute either of the following commands to install OVMF, if not already installed.
   1. Stable builds from Fedora repos
      Since June 2016, OVMF is available in the default Fedora repositories as a part of the edk2-ovmf package. It would most likely be installed already on a default Fedora installation and the package also includes the firmware for secureboot.

      $ sudo dnf install edk2-ovmf -y
      

   2. Nightly builds from custom repo
      The nightly builds of OVMF can be found in a custom repository maintained by Gerd Hoffmann on his personal site where a collection of QEMU/KVM firmware, including EDK2/OVMF can be found. Due to their experimental nature, these builds can be occasionally broken.

      $ sudo dnf install dnf-plugins-core
      $ sudo dnf config-manager --add-repo http://www.kraxel.org/repos/firmware.repo
      $ sudo dnf install edk2.git-ovmf-x64
      

2. Navigate to the following directory where the OVMF assets are installed.

   $ cd /usr/share/edk2/ovmf
   $ ls
   EnrollDefaultKeys.efi
   OVMF_CODE.fd
   OVMF_CODE.secboot.fd
   OVMF_VARS.fd
   OVMF_VARS.secboot.fd
   Shell.efi
   UefiShell.iso
   

3. Assets from this folder would be continually referred to in the dealings with QEMU.
