tempest role fails on AIO

[DimGR]

Hello

I have been trying to install AIO on real hardware with OS ubuntu bionic and centos 7 and i always get the same error about tempest . I have tried 17.x.x and 18.1.4 releases all with the same errors

the error log is pasted here:

if i ignore the error and login in to horizon everything seems normal but when i try to create a network the instances never schedule so i assume this has something to do with the failing tempest role
thanks

Hello,

my playbook fails in the same step - tempest tests. spec-wise the machine has more than the recommended resources. The same installation succeeded in a VM environment on a host with 24GB of RAM

Hi ,

i tried AIO again today on centos7 and git cloned 18.0.0.0 and tempest tests from the role passed.
I do not know this was failing miserably in all of my attempts . I have not made any changes in the AIO role , i run with the default values .

I'd be happy to know the root cause for the errors above
