If it's easily reproducible, then the simplest way to troubleshoot is to use another distro as guest, or at least another kernel. You said that this guest runs docker, right? Then it should be easy enough to try install a new guest with another distro (e.g. ubuntu, centos, whatever), install docker on it, and try to replicate your problem. If the culprit is bridge/netfilter module, you could probably test with installing another kernel. Try kernel:HEAD? https://doc.opensuse.org/documentation/leap/reference/html/book.opensuse.reference/cha-tuning-multikernel.html#sec-tuning-multikernel-latest In any case, those two methods can help verify whether the problem is in the kernel (module), or something in leap userland (including its docker version). -- Fajar -- To unsubscribe, e-mail: [email protected] To contact the owner, e-mail: [email protected]
