Can you post the output of this from the host? cat /proc/cpuinfo | grep platform If it reports "PowerNV" then things should be working, so the error needs investigation. If it reports "pSeries", then that's not a normally supported scenario for running KVM (since your host is already running as virtualized pSeries partition running on top of the pHyp hypervisor rather than KVM). You *might* have KVM support via 'PR' mode as opposed to the normal 'HV' mode, but that's generally used to do nested virtualization on top of a KVM HV guest. To do it on top of a pHyp guest partition is probably not something that's been actively tested. I'd assume you're using PowerNV host, but you mentioned "PowerVM" earlier which is synonymous with pHyp, so it warrants confirming. > > -- > You received this bug notification because you are a member of qemu- > devel-ml, which is subscribed to QEMU. > https://bugs.launchpad.net/bugs/1563887 > > Title: > qemu-system-ppc64 freezes on starting image on ppc64le > > Status in QEMU: > New > Status in linux package in Ubuntu: > Confirmed > Status in livecd-rootfs package in Ubuntu: > New > Status in qemu package in Ubuntu: > Confirmed > > Bug description: > qemu-system-ppc64 running on Ubuntu 16.04 beta-2 fails to start an > image as part of the certification process.
