Hi Greg, Thanks for following up. (Meanwhile I posted this Q to KVM-PPC and QEMU-PPC too. On the latter it's https://lists.nongnu.org/archive/html/qemu-ppc/2021-08/msg00416.html and on the further it didn't register yet.) First I believe KVM-QEMU and "PowerKVM" are different - the latter was a KVM fork maintained by IBM. The further is just the KVM and QEMU repo. Did IBM their contributions so PowerKVM was upstreamed, you tell me. Are you saying that KVM-QEMU has all relevant Power9 support already, for a Linux host OpenBSD as a guest on bare metal ("powernv" mode)? In this case why would there be any relevance in OpenBSD implementing pseries. Best regards
