Following the other Xenial LXD bugs (1554675, 1551440, 1557747) I was able to bootstrap a Xenial controller on x86, but no lock on s390.

I am posting here as it is similar, but not the same stack trace:

Cheryl,
Let me know if you think this is a related issue already fixed for beta4, or if I should open a new bug.

-thanks,
Antonio
