What does `ppc64_cpu --info` report? The original bug had some output that suggested SMT was enabled: > cpu_cores: Number of cores present =3D 8 > cpu_coreson: Number of cores online =3D 8 > cpu_smt: SMT=3D8 But AFAIK, SMT should be disabled in the host (ppc64_cpu --smt off) and left to individual guests to enable/disable in guest mode. For KVM on powernv host kernel at least... original bug suggested PowerVM mode: > Bug description: > qemu-system-ppc64 running on Ubuntu 16.04 beta-2 fails to start an > image as part of the certification process. This on an IBM ppc64le in > PowerVM mode running Ubuntu 16.04 beta-2 deployed by MAAS 1.9.1. There > is no error output. which I'm assuming didn't actually mean PowerVM instead of powernv+KVM? Or was this actually a PowerVM partition trying to run a KVM guest?
