So, the problem is that as of qemu 2.11, Power arch guests don't start, since libvirt ppc code is looking for the string POWER to determine whether the system supports the model at hand. Comment from our qemu maintainer: "There was a rework in QEMU side to allow case-insensitive specification of CPU models. As a side-effect of that some models no longer show up as all caps in -cpu ? / query-cpu-definitions. This requires libvirt changes to avoid relying on specific capitalized models." Are you concerned that we SHOULD be looking for case-sensitive models in libvirt? Is this a problem absent qemu? -Scott -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
