In my environment, I used kata with containerd.  I configured plugins for kata in /etc/containerd/config.toml with two kata runtimes -- kata and kata-qemu.  If there is no plugins configuration in config.toml file, is there a default runtime name that I can use?  I am invoking the kata runtime name trough the CRI API (RuntimeHandler).

        [plugins.cri.containerd.runtimes.kata]
          runtime_type = "io.containerd.kata.v2"
          [plugins.cri.containerd.runtimes.kata.options]
            ConfigPath = "/etc/kata-containers/configuration.toml"
        [plugins.cri.containerd.runtimes.kata-qemu]
          runtime_type = "io.containerd.kata-qemu.v2"
          [plugins.cri.containerd.runtimes.kata-qemu.options]
            ConfigPath = "/opt/kata/share/defaults/kata-containers/configuration-qemu.toml"

$ kata-runtime version
kata-runtime  : 1.9.1
