This causes some software such as LLVM to notice the problem (32-bit cpu with 64-bit capability reported in the cpuid flag) and produce various error messages. The simple solution would be to upgrade this definition to use the Sledge= hammer family (15) instead. = [1] https://en.wikipedia.org/wiki/List_of_AMD_CPU_microarchitectures To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1860575/+subscriptions
