Add --virt-uefi to boot the VM using OVMF
This requires OVMF to be setup on the system, and for the kickstart to create a /boot/efi/ partition. You can then use it to create UEFI bootable partitioned disk images.

Creating UEFI disk images with virt
|
||||
-----------------------------------
|
||||
|
||||
Partitioned disk images can only be created for the same platform as the host system (BIOS or
|
||||
UEFI). You can use virt to create BIOS images on UEFI systems, and it is also possible
|
||||
to create UEFI images on BIOS systems using OVMF. You first need to setup your system with
|
||||
the OVMF firmware. The details can be `found here linux-kvm OVMF page <http://www.linux-kvm.org/page/OVMF>`_
|
||||
but it amounts to:
|
||||
|
||||
1. Download the firmware.repo from `Gerd Hoffmann <https://www.kraxel.org/repos/>`_ and install it
|
||||
in /etc/yum.repos.d/
|
||||
|
||||
2. Install the edk2.git-ovmf-x64 package
|
||||
|
||||
3. Copy /usr/share/edk2.git/ovmf-x64/OVMF_CODE-pure-efi.fd to /usr/share/OVMF/OVMF_CODE.fd
|
||||
|
||||
4. Copy /usr/share/edk2.git/ovmf-x64/OVMF_VARS-pure-efi.fd to /usr/share/OVMF/OVMF_VARS.fd
|
||||
|
||||
Now you can run livemedia-creator with ``--virt-uefi`` to boot and install using UEFI::
|
||||
|
||||
sudo livemedia-creator --make-disk --virt-uefi --iso=/path/to/boot.iso \
|
||||
--ks=/path/to/fedora-minimal.ks
|
||||
|
||||
Make sure that the kickstart you are using creates a /boot/efi partition by including this::
|
||||
|
||||
part /boot/efi --fstype="efi" --size=500
|
||||
|
||||
.. note::
|
||||
When using the resulting image with the current version of OVMF (edk2.git-ovmf-x64-0-20151103.b1295.ge5cffca)
|
||||
it will not boot automatically because there is a problem with the fallback path.
|
||||
You can boot it by entering the UEFI shell and running EFI/fedora/shim.efi and
|
||||
then using efibootmgr to setup the correct boot entry.
