[AMD Official Use Only - Internal Distribution Only]

Thank you Fabiano,
Will try the deployed version first,
One more to check please - In my understanding - Docker doesn't yet support the containerd shimv2 architecture directly, Kata 2.0.0 won't work with Docker ?
Is this correct ? 
Any workarounds.

--Best Regards

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%2Fkata-containers%2Fpackaging%2Ftree%2Fmaster%2Fkata-deploy&data=04%7C01%7Csandeep.gupta%40amd.com%7C77df3c891c8a426c4e6208d8b083a31d%7C3dd8961fe4884e608e11a82d994e183d%7C0%7C0%7C637453426728389564%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=FhnMOeGRaH0sFtZ%2BhLwvfqm%2BPY2jUiVt6cdSHirE0Ro%3D&reserved=0

I hope that helps!
