# UEFI Boot
|
||
|
|
|
||
|
|
Cloud Hypervisor supports UEFI boot through the utilization of the EDK II based UEFI firmware.
|
||
|
|
|
||
|
|
## Building UEFI Firmware
|
||
|
|
|
||
|
|
To avoid any unnecessary issues, it is recommended to use Ubuntu 18.04 and its default toolset. Any other compatible Linux distribution is otherwise suitable, however it is suggested to use a temporary Docker container with Ubuntu 18.04 for a quick build on an existing Linux machine.
|
||
|
|
|
||
|
|
The commands below will compile an OVMF firmware suitable for Cloud Hypervisor.
|
||
|
|
|
||
|
|
```shell
|
||
|
|
sudo apt-get update
|
||
|
|
sudo apt-get install uuid-dev nasm iasl build-essential python3-distutils git
|
||
|
|
|
||
|
|
git clone https://github.com/cloud-hypervisor/edk2 -b ch
|
||
|
|
cd edk2
|
||
|
|
. edksetup.sh
|
||
|
|
git submodule update --init
|
||
|
|
|
||
|
|
echo "ACTIVE_PLATFORM=OvmfPkg/OvmfCh.dsc" >> Conf/target.txt
|
||
|
|
echo "TARGET_ARCH=X64" >> Conf/target.txt
|
||
|
|
echo "TOOL_CHAIN_TAG=GCC5" >> Conf/target.txt
|
||
|
|
|
||
|
|
make -C ./BaseTools
|
||
|
|
build
|
||
|
|
```
|
||
|
|
|
||
|
|
After the successful build, the resulting firmware binaries are available under `Build/OvmfCh/DEBUG_GCC5/FV` underneath the edk2 checkout.
|
||
|
|
|
||
|
|
## Using OVMF Binaries
|
||
|
|
|
||
|
|
Any UEFI capable image can be booted using the Cloud Hypervisor specific firmware. Windows guests under Cloud Hypervisor only support UEFI boot, therefore OVMF is mandatory there.
|
||
|
|
|
||
|
|
To make Cloud Hypervisor use UEFI boot, pass the `OVMF.fd` file path as an argument to the `--kernel` option. The firmware file will be opened in read only mode.
|
||
|
|
|
||
|
|
The same firmware can be used with Cloud Hypervisor or with QEMU. This is particularly useful if using QEMU for the preparation phase.
