Help, how to use krunvm to run docker or k3s

[wtry]

Thanks for providing such an excellent tool!
But I haven't found how to use this tool
Using docker on macOS is very complicated. Docker can only be installed in vm, which is very resource-intensive and inefficient.
After seeing this tool, I want to create a vm, and then run docker or k3s in the vm, instead of qemu, docker for mac or other virtual machines, but I have no success, no matter it is docker, podman, k3s, can't Started in the image of krunvm, is there any way to use docker or k3s in the image of krunvm?

Running regular OCI containers doesn't fit quite well with the microVM model, as they require a context that provides a significant amount of features. For this purpose, podman (which is also available on macOS) is a much better option.

Seems like newer versions of crun need BPF. I've just added support for that on aarch64 (was already enabled in x86_64) in libkrunfw-3.6.0. Should work after updating your packages:

That said, I still think podman-machine is a better option if you intent to mostly run podman commands. Or, alternatively, using krunvm directly with the container you intend to run.
