Confirmed.

[Nate Johnston (nate-johnston)]

I put in a patch to cap the level of testtools in test-requirements: https://review.openstack.org/#/c/276307/

[Kevin Bringard (kbringard)]

FYI: Also affecting the stable/liberty branch of openstack/nova

[Kevin Bringard (kbringard)]

Specifically:

gate-grenade-dsvm-partial-ncpu
gate-grenade-ddvm

[Ken'ichi Ohmichi (oomichi)]

This problem happens on Tempest gate also now.

[Brant Knudson (blk-u)]

I wonder why it says keystone requires fixtures. fixtures isn't in keystone's requirements.txt, and there's no reason for keystone to depend on fixtures at runtime.

[Ryan Hsu (rhsu)]

Also seeing this when stacking with the stable/kilo Devstack branch.

[Ihar Hrachyshka (ihar-hrachyshka)]

Was fixed recently.
