Kata just released a new version, it is the only thing that I've found easy to setup with k8s... though my experience running Docker-in-Kata hasn't been very good.
We were looking at Kata as well, especially as an 'easier' firecracker, though I forgot why we didn't go further, and I've been curious why they seem to get so little attention in practice?
I believe part is portability, as they may require nested virtualization features to be available, and maybe QEMU overhead. Maybe also something about use in China vs elsewhere?
They (and QEMU) have been around a long time and some major companies are supporting it...
