4 years ago @Jason-ZW thanks, but the logs sections is empty, did you run the test after enabling full debug?

4 years ago Thanks for your reply. I follow these documents to enable the full kata debug log. But still no logs sections.
Am I something wrong?

4 years ago @Jason-ZW thanks, looks like the kata-collect-data.sh is looking for errors in the journal, could you run sudo journalctl -b -t kata-proxy -t kata-shim -t kata-runtime ?

4 years ago @devimc Still no entry. Should I copy the /lib/modules to the container dir?

4 years ago Hi @Jason-ZW , it's seem that you using contaienrd.
If yes, can you try to add pod_annotations = ["io.katacontainers.*"] to /etc/containerd/config.toml. Like this:
[plugins."io.containerd.grpc.v1.cri".containerd.runtimes.kata]
runtime_type = "io.containerd.kata.v2"
pod_annotations = ["io.katacontainers.*"]@liubin Thanks for your help. After configuring as you said, the kernel still cannot be loaded.

4 years ago Then, can you run
$ sudo cat /run/containerd/io.containerd.runtime.v2.task/k8s.io/0b9db04144df476c5df84b7ef785abfdd309757525a6d4c71ea26880e6756835/config.json | jq .annotationsto see whether the annotations have passed to Kata? Where 0b9db04144df476c5df84b7ef785abfdd309757525a6d4c71ea26880e6756835 is the sandbox id.

}I tested on my local and it worked.
I noticed that you are running systemctl restart contained, is it a typo or what you really run?
+ systemctl restart containerd
- systemctl restart contained@liubin Oh, I found I missed annotations io.katacontainers.config.agent.kernel_modules. Now it works. Thanks a lot for your help.
Description of problem
Using osbuilder with
KERNEL_MODULES_DIRenv built the image which includes the loadable kernel modulebr_netfilterI can successfully use the debug console load the loadable kernel module
br_netfilter. But using pod annotation the module loaded failed, exec into the pod there is no/sys/module/br_netfilter.Expected result
Using annotation can load the loadable kernel module
Actual result
Can not using pod annotation load the kernel module, but can using debug console
modprobe br_netfilter
