described in [Building Kata Containers kernel](https://github.com/kata-containers/packaging/tree/master/kernel).
For further details on building and installing guest kernels, see [the developer guide](https://github.com/kata-containers/documentation/blob/master/Developer-Guide.md#install-guest-kernel-images).
There is an easy way to build a guest kernel that supports Intel GPU:
```
## Build guest kernel with https://github.com/kata-containers/packaging/tree/master/kernel
# Prepare (download guest kernel source, generate .config)
$ ./build-kernel.sh -g intel -f setup
# Build guest kernel
$ ./build-kernel.sh -g intel build
# Install guest kernel
$ sudo -E ./build-kernel.sh -g intel install
/usr/share/kata-containers/vmlinux-intel-gpu.container -> vmlinux-5.4.15-70-intel-gpu
/usr/share/kata-containers/vmlinuz-intel-gpu.container -> vmlinuz-5.4.15-70-intel-gpu
```
Before using the new guest kernel, please update the `kernel` parameters in `configuration.toml`.
```
kernel = "/usr/share/kata-containers/vmlinuz-intel-gpu.container"
```
