All I'm tryin is to get 5.2 running as a kvm/qemu guest. Now I even tried an non-updated 5.1 with this kernel-xen as a host system: http://people.centos.org/hughesjr/kernel/5/bz443853/x86_64/ Still no luck. Still getting that "powernowk8_init" guest kernel crash while installing. Maybe I made something wrong from ground up using the 5.2 x86_64 installation image. Under debian that worked, so it should work here as well. Now I tend to use debian a base and virtualize my systems there. It seems to be the only way that works for me (already tried that). But I'd prefer to use CentOS. So if you can help me, I'll be lucky. Otherwise I'll have to fight my way through using debian... (that's no menace ;-) ) Regards Michael
