Hi Sandeep, Correct - Docker doesn't support shimv2 yet. However, getting Kata 2.x running with containerd is very simple and the CLI for containerd is reasonably similar to docker: # Kata 1.x $ docker run --runtime=kata-runtime ... # Kata 2.x $ ctr run --runtime io.containerd.kata.v2 ... See [1] for further details.

I can discuss this Issue in, Kata AC call in 2021 on January 5th.
We can, but I think it may be easier to debug this via e-mail or Slack. So, I'd like to ask you a few questions that will help me (and hopefully others) to understand where the error is coming from. * When you're using 2.x, you're only replacing the runtime binary, but also the image and the agent inside it, right? - The reason I'm asking is because 2.x runtime doesn't speak the same language as the 1.x agent. * Is your agent built using musl or gnu libc? If you want to give it a quick try just to ensure kata 2.0 works for you before you start hacking the code, I'd suggest using https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com... I hope that helps!
