Right, it's POWER7 PPC64 BE with kvm_pr. If this should be fixed for QEMU 2.8 please add it to http://qemu-project.org/Planning/2.8 and I'll track it (i.e. won't release before it's resolved). If this is a known issue that will be in QEMU 2.8 please add it to http://qemu-project.org/ChangeLog/2.8#Known_issues. Stefan
