[Non-Deterministic behavior] CentOS7 Online CI leg failing infrequently

Fails at 'Run smoke tests in tarball stage'

Example failure : Link CentOS Online

This is sign that system probably does not have IPv6 configured. You can try to collect output of ipconfig -a or ip addr show

@wfurt This doesn't happen every-time. I can try to get ipv6 info. The session is not interactive so it will be hard to get it for this particular run though.

[wfurt]

understand. it may be worth of adding this as build step rather than attempt to collect after failure. The output should be reasonably small. You can also watch if this fails only on particular build node.

Closing this for the time being as the issue is fairly infrequent and fetching ip info from docker containers in CI could involve tweaks to add ifconfig utility.
