zCX/Openshift Multi-Architectur Support with VMWare & zCX

With OpenShift 4.14, OpenShift supports Multi-Architectur setup with the Control Nodes on x86 and e.g. Worker Nodes on s390x (zCX). Unfortunately, VMWare is a not supported plattform. Without that support, we'll never get the chance to go to production with zCX/OpenShift, because we can't provide the capacity with required zIIPs to rebuild the OpenShift infrastructure required in our shop.

Also, with Multi-Arch support together with VMWare, we could reduce the required manpower, because no new clusters would be needed.


With the current support with OCP 4.14 without VMWare support, we can't use the OCP architecture we are dependent on. We can't use some OCP features with agnostic installer, everything would need to build new.


So, OpenShift have to support Multi-Arch with the Master Nodes on x86 with VMWare/vSphere.
