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
