What is OVMF?
OVMF is a port of Intel’s tianocore firmware to the qemu virtual machine. This allows easy debugging and experimentation with UEFI firmware; either for testing Ubuntu or using the (included) EFI shell.
Is QEMU UEFI or BIOS?
Most Qemu software runs BIOS (Legacy) initialization software. In many cases, a user may want to run Qemu with UEFI instead of BIOS. Additionally, a user may prefer run Qemu in command line or graphically with Aqemu.
How do you run OVMF?
How to run OVMF with QEMU or KVM.
- Pre-requisites.
- Choose the correct processor architecture.
- Setup a BIOS directory for OVMF QEMU.
- Create a directory, and cd to the directory.
- Next, create a directory to use as a hard disk image for QEMU.
- Run QEMU using OVMF.
- Optional: Point directly to UEFI firmware in edk2/Build directory.
What is edk2 OVMF?
The Open Virtual Machine Firmware (OVMF) project aims. to support firmware for Virtual Machines using the edk2. code base.
What is qemu X86_64?
What is Qemu-System-X86_64? … QEMU is an open source virtual machine hardware emulation hypervisor. It’s similar to VMware or VirtualBox. It is not normally found on a Mac.
What is Ovmf_vars FD?
OVMF_CODE. fd contains the actual UEFI firmware, and OVMF_VARS. fd is a “template” used to emulate persistent NVRAM storage. All VM instances can share the same system-wide, read-only OVMF_CODE. fd file from the ovmf package, but each instance needs a private, writable copy of OVMF_VARS.
What is OVMF in Linux?
The Open Virtual Machine Firmware (OVMF) is a project to enable UEFI support for virtual machines. Starting with Linux 3.9 and recent versions of QEMU, it is now possible to passthrough a graphics card, offering the virtual machine native graphics performance which is useful for graphic-intensive tasks.
Does QEMU use UEFI?
UEFI for x86 QEMU/KVM VMs is called OVMF (Open Virtual Machine Firmware). It comes from EDK2 (EFI Development Kit), which is the UEFI reference implementation.

How do you use QEMU for debugging?
This is how I generally use qemu for debugging: Creates two serial ports: one for the OVMF debug output, and one for a usable serial console Uses a LVM block device, /dev/local/virt-ovmf as the local storage
How do I boot a QEMU machine with BIOS?
For the simplest use-case, you can boot the machine like this (with bios.bin in the current directory): qemu-system-x86_64 -L . The -L . option tells qemu to look in the current directory for the bios.bin firmware image. This will allow you to play with the firmware setup screens, and the EFI shell.
