Comment 1 for bug 1605742

It is repeatable issue.

Next gate job execution failed with same errors: http://logs.openstack.org/09/342309/8/check/gate-openstack-ansible-dsvm-commit/db750e1/console.html#_2016-07-22_21_12_12_401011

I've repeated it on my environment.

Looks like potential cause of issue can be related with some incompatibility between tempest and nova.

Tempest version: c2c90574a78c7704f06e8fac279c4f1d11365993 (git branch output[1])
Nova version: 98b38df57bfed3802ce60ee52e4450871fccdbfa (git branch output[2])
