      In the web console, it is erroneously possible to define multiple CPU threads for a VM based on s390x architecture. If you define multiple CPU threads, the VM enters a CrashLoopBackOff state with the error qemu-kvm: S390 does not support more than 1 threads. (CNV-56890)

      Description of problem:

      In Openshift console> Virtualization perspective, a s390x based VM configuration CPU topology currently allows editing the thread to more than 1. But qemu-kvm for s390x doesn’t allow me to define threads other than 1 as designed. So till this UI issue is fixed, if anyone modifies thread value to 1, VM goes into crashloopbackoff with error “qemu-kvm: S390 does not support more than 1 threads.”
