As x86_64 has updated the guest kernel to enable EFI support for NEMU, because OVMF that is used by NEMU is an EFI firmware. Although the NEMU is not ready for Arm64, we'd better to enable EFI support in kernel to keep sync with x86_64. Fixes #228 Signed-off-by: Wei Chen <wei.chen@arm.com>
Build Kata Containers Kernel
This document explains the steps to build a compatible kernel with Kata Containers. To do this use build-kernel.sh, this script automates the process to build a kernel for Kata Containers.
Setup kernel source code
./build-kernel.sh setup
The script ./build-kernel.sh tries to apply the patches from
${GOPATH}/src/github.com/kata-containers/packaging/kernel/patches/ when it
sets up a kernel. If you want to add a source modification, add a patch on this
directory.
The script also adds a kernel config file from
${GOPATH}/src/github.com/kata-containers/packaging/kernel/configs/ to .config
in the kernel source code. You can modify it as needed.
Build the kernel
After the kernel source code is ready it is possible to build the kernel.
./build-kernel.sh build
Install the Kernel in the default path for Kata
Kata Containers uses some default path to search a kernel to boot. To install on this path, the following command will install it to the default Kata containers path.
./build-kernel.sh install
