Firmware). It comes from EDK2 (EFI Development Kit), which is the UEFI

reference implementation.

Since June 2016, OVMF is available in Fedora repositories. All you need
|

to have installed is `edk2-ovmf` RPM. Furthermore, it should be now a

dependency of the package, so you probably have it installed already.

Gerd Hoffmann, Red Hatter and QEMU developer, has a dnf repo on his

personal site that provides nightly builds of a whole bunch of QEMU/KVM
|
||||
firmware, including EDK2/OVMF.

|
||||
|
||||
Here's how to pull down the nightly builds for x86:
|
||||
|
||||
` sudo dnf install dnf-plugins-core` +
|
||||
` sudo dnf config-manager --add-repo `http://www.kraxel.org/repos/firmware.repo[`http://www.kraxel.org/repos/firmware.repo`] +
|
||||
` sudo dnf install edk2.git-ovmf-x64`

||||

||||

|
||||
[…]# sudo dnf install edk2.git-ovmf-x64

Optionally Configure libvirtd to advertise UEFI support

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|

== Optionally Configure libvirtd to advertise UEFI support
|
||||
|
||||
Libvirt needs to know about UEFI->NVRAM config file mapping, so it can
|
||||
advertise it to tools like virt-manager/virt-install. On Fedora 22 and
|
||||
later, libvirt packages are configured to look for the nightly build
|
||||
paths, so this will work out of the box.

However, if you want to use custom binaries, you will need to edit the

nvram variable in /etc/libvirt/qemu.conf and restart libvirtd.

Create a new VM in virt-manager. When you get to the final page of the
|
||||
'New VM' wizard, do the following:
|
||||
|
||||
* Click 'Customize before install', then select 'Finish'
|
||||
* On the 'Overview' screen, Change the 'Firmware' field to select the
|
||||
'UEFI x86_64' option.
|
||||
* Click 'Begin Installation'
|
||||
* Click "Customize before install", then select "Finish"
|
||||
* On the "Overview" screen, change the "Firmware" field to select the "UEFI x86_64" option.
|
||||
* Click "Begin Installation"
|
||||
* The boot screen you'll see should use `linuxefi` commands to boot the
|
||||
installer, and you should be able to run `efibootmgr` inside that
|
||||
system, to verify that you're running an UEFI OS.

other curious parties. This requires configuring the VM to use UEFI, so

it builds upon the previous UEFI steps.
