The 3.10 works fine with Docker. There are a couple of things like criu that require things in the 4.1x kernel but this is not essential. I run OpenShift Origin 3.9 under docker 1.13 under the 3.10 kernel.

The 3.10 kernel version does not support KVM virtualization and containers on IBM z Systems. Both of these features are supported on the 4.14 kernel on IBM z Systems - this offerring is also referred to as Structure A. I run z/VM as the hypervisor, so I am assuming I would need RHEL7 Structure A to do containers?

Another thing to keep in mind is that the s390utils-* releases are different. For RHEL it's 1.23.0 and for RHEL Structure A it's 2.1.0. > It looks like the minimum RHEL 7.5/RHEL 7.5 Structure A machine model > requirement hasn't changed since RHEL 7.4, so it's z196/z114 > processors or higher, which includes all LinuxONE machines. > > I don't have a strong view on the "right" approach for Linux release > streams.
