I'm requesting +1/-1 reporting permission (non-voting) to Nova for the 
s390x libvirt/kvm (zKVM) nova ci [1] (check pipeline only).

We already got this permission granted in the Nova Meeting on February, 
2nd 2017 [4], but after our CI went down on May 16 for a couple of 
weeks, we somehow (technically) lost the permission. As we already got 
the permission granted in the past, the CI is already sending +1/-1 to 
Gerrit. But it is not showing up in the list of CIs next to Zuul, 
Jenkins check, IBM PowerVM.. and therefore also not in the CI watch [3] 
(what it did before). Getting added to this list again is the missing piece.

* Gerrit Acount: ibm-zkvm-ci

* Gerrit query on patches where the CI commented: [2]

* Proposal for naming: IBM zKVM CI

For any questions feel free to reach out to me (andreas_s) or to markus_z!


Why did it take so long? Well, we took the chance and designed the CI 
totally new. Now it's using the current versions of nodepool, zuul and 
Jenkins - the transition to zuul v3 is planned as soon as it is running 
stable upstream. We're using KVM on KVM (the first version was using KVM 
on z/VM) and daily image builds via DIB. We moved everything (including 
zuul, nodepool & jenkins) to the z (s390x) platform (in the first 
version most parts where still running on pretty old x86 HW attached to 
a fragile storage system). Now we also have a test environment in place 
that allows us testing patches (e.g. the transition to zuulv3) before 
applying them on the production system.
