Before you start, please NOTE: this guide does not cover rootless containers!

On an hypervisor with LXD installed, create a new container, ensuring that -c security.nesting=true -c security.privileged=true is set:

lxc launch -c security.nesting=true -c security.privileged=true images:fedora/35 my-container

If the container already exists, set this parameter through lxc config:

lxc config set my-container security.nesting=true
lxc config set my-container security.privileged=true
