Ok. I found virt-v2v which will convert .img files between different VM types.
Thanks.

The "image" that I was referring to is a Docker or OCI image. It's a
completely new entity from anything that you'd find in Xen. It's basically
a tar file formatted in a certain way that Kubernetes knows how to load, to
create a container. You create an image with the "docker" or (more modern)
"podman" command, using a Dockerfile, which describes how to assemble the
image.
If you have experience with LXCs, containers are close to that.
