Hi Eduard,

I suspect, from looking at the above error, that you are re-using the 
slave instance on subsequent runs of Jenkins jobs. If you are doing this 
(as opposed to using something like nodepool to keep a pool of 
single-use slave VMs around for running Jenkins jobs, then you will need 
to run some sort of cleanup/reset script after the Jenkins job completes.

Akihiro Motoki has a nice repo with scripts you can use for this purpose:

https://github.com/amotoki/devstack-tools

(see the devstack-cleaner.sh script)

For best results, however, the upstream infrastructure team has 
definitely found that using single-use slave VMs, managed by nodepool, 
is the safest and cleanest way to handle Jenkins jobs that involve 
devstack-gate (like the jobs detailed in my joinfu.com posts).

All the best,
