The error message for QEMU 2.8 means that it fails to initialize the machine in ppc_cpu_parse_features() which is a bit late. For QEMU 2.9, it fails at the right beginning in xics_system_init(), before the CPUs are initialized, which is better, I think. I admit the message is not very clear, but the host kernel is using a dev config. > On Qoriq if i pass the -cpu e500 (normal thing) all is working right qemu > 2.9rc1 > all boot and so and so. but you must be changing the machine right ? > On G5 the -cpu variable dont fix the issue. with which machine ? > I can build a new kernel release , usually mine dont have xics enabled > because G5 > dont have that feature, if needed i can enable it for testing.** Yes that would be interesting.
