QEMU complains about -cpu host on an AMD machine: warning: host doesn't support requested feature: CPUID.80000001H:EDX [bit 0] For bits 0,1,3,4,5,6,7,8,9,12,13,14,15,16,17,23,24. KVM_GET_SUPPORTED_CPUID and and x86_cpu_get_migratable_flags() don't handle the AMD CPUID aliases bits, making x86_cpu_filter_features() print warnings and clear those CPUID bits incorrectly. To avoid hacking x86_cpu_get_migratable_flags() to handle CPUID_EXT2_AMD_ALIASES (just like the existing hack inside kvm_arch_get_supported_cpuid()), simply move the CPUID_EXT2_AMD_ALIASES code in x86_cpu_realizefn() after the x86_cpu_filter_features() call. This will probably make the CPUID_EXT2_AMD_ALIASES hack in kvm_arch_get_supported_cpuid() unnecessary, too. The hack will be removed in a follow-up patch after v2.6.0.
