Thank you for the code review and that you point out the 'failed to
resolve hostname' issue.
It looks like in zdtm.py when the --remote-lazy-pages option is
specified, only --port (12345) is being set, and --address was omitted.
This is causing the failure. I will resend the patch series with this fixed.
