I'm running linux-3.16 on a ppc64 built with kvm-pr as a module (no kvm-hv). I manually modprobe the kvm-pr module after boot and realize performance gains on my ppc64 guest in qemu. According to 'make menuconfig', kvm-pr allows some virtualization of a guest whose architecture does not match that of the host. I'm wondering if qemu will, using this module, support a x86-64 guest on a ppc64 host. I've tried to run such a configuration and have received an error that KVM is not supported. I'm wondering if I built incorrectly or am not passing a necessary command line parameter. Understandably, qemu cannot support such a configuration when using kvm-hv.
