This is reproducible over 23 runs of this happened tonight, sounds like a regression to me:

I will update here with additional information once I find it.

Last successful run was with this patch:

https://gerrit.ovirt.org/#/c/66416/ (vdsm: API: move vm parameters fixup in a method)

Known to start failing around this patch:

https://gerrit.ovirt.org/#/c/67647/ (vdsmapi: fix a typo in string formatting)

Please notes that we do not have gating implemented yet, so everything that was merged in between those patches might have caused this (not necessary in vdsm project).

Anton.
