Summary

In this PR, running separate instances of firecracker-containerd also produces the same flake. Adding kernel message logging on failure might help us debug the cause.

Ref: #1113

Hmm, the kernel messages don't seem to help.

I think that even if this doesn't help for the current flake issue, it might help us debug for future errors.

Kernel messages are unlikely to be helpful; it would be more appropriate to collect Firecracker/containerd/vhive logs.

I agree, although I think that there will be no harm done with including the kernel messages to debug containerd for a more comprehensive logging. This is also used in containerd's CI.
