Ls -l usr/share/edk2.git/ovmf-圆4/OVMF-pure-efi.fd Rpm2cpio edk2.git-ovmf-圆.rpm | cpio -idmv If you download “jenkins/edk2/edk2.git-ovmf-圆.rpm”, then you can pull “OVMF-pure-efi.fd” from the package. Prebuilt images of OVMF were available at. $ sudo aa-enforce /usr/sbin/libvirtd (enforce again) $ sudo aa-complain /usr/sbin/libvirtd (complain only) If ERROR – internal error: cannot load AppArmor profile ‘libvirt. Stackoverflow, git submodule or else you get BrotliCompress.c constants.h fatal error because file not found (Logo.bmp dropped at MdeModulePkg/Logo/Logo.bmp) (examples of scripting changing of Conf/target.txt) (prebuilt binary images, no need to build) Tianocore, TianoCore open source UEFI implementation If you have to restart the host and have issues with reaching grub and only the UEFI shell is displayed, then read here. If you are interested in using this image to boot a VM on KVM, read my article here. This will automatically use the virt-viewer and show you a screen that looks like the screenshot below: $ qemu-system-x86_64 -bios Build/OvmfX64/RELEASE_GCC5/FV/OVMF.fd $ sudo apt-get install qemu-kvm qemu libvirt-bin virt-manager virtinst bridge-utils cpu-checker virt-viewer # show relative path to imageĪs a validation that this is a usable firmware image, let’s run a quick smoke test using QEMU, an open-source emulator/virtualizer. When build finishes successfully, the final OVMF images are in the ‘Build’ directory. $ sed -i -e 's/^ACTIVE_PLATFORM.*/ACTIVE_PLATFORM = OvmfPkg/OvmfPkgX64.dsc/' Conf/target.txt $ sed -i -e 's/^TOOL_CHAIN_TAG/TOOL_CHAIN_TAG = GCC5/' Conf/target.txt $ sed -i -e 's/^TARGET_ARCH.*/TARGET_ARCH = X64/' Conf/target.txt Here we are setting the values to generate a 64 bit using gcc 5 just like the command line above. OR you can modify ‘Conf/target.txt’ with these same values. First, you can simply specify them as parameters to the build like below: $ build -a X64 -t GCC5 -b RELEASE -p OvmfPkg/OvmfPkgX64.dsc You need to specify which version of OVMF you want to build, there are two ways to do that. Now go into the source directory, and run a make which populates the “Conf” directory.

$ sudo apt-get install build-essential git uuid-dev iasl nasm -y In this article, I will show how to build the latest OVMF image from source. UUEFI is designed to eventually replace the BIOS firmware interface.

OVMF is an open-source project that implements the Unified Extensible Firmware Interface (UEFI) specification.
