power9 compatibility mode, which AFAICT is simply not defined at all in QEMU. Umm.. what? It's right there in target/ppc/compat.c. Or are you looking at downstream - maybe it hasn't been backported yet.

One more issue I've noticed: $ /usr/libexec/qemu-kvm \ -nodefaults \ -M pseries,accel=kvm \ -cpu POWER9 qemu-kvm: Unable to find sPAPR CPU Core definition Since the recommended configuration for POWER8 guests is to use <cpu mode='custom'> <model>POWER8</model> </cpu> I would expect the above command line to work so that POWER9 guests can be configured in a similar manner. That seems bug-worthy to me, should I go ahead and file it? Uh, yeah. Again, I'm pretty sure that's already working upstream.
Yeah, I've been looking at downstream. I'll try again with upstream and file bugs as needed. -- Andrea Bolognani / Red Hat / Virtualization
