Comparing x86_64 and aarch64 build host runqemu command lines from wic.Wic2.test_efi_plugin_plain_systemd_boot_qemu_aarch64 selftest, two things pop up. aarch64 still enables KVM via "-enable-kvm". This is despite QEMU_USE_KVM = "" in the bitbake build config. Oh, this is only applied to the build configuration and bitbake build command but removed before runqemu is called. I can try to apply this config also for runqemu. This pattern is used in several tests. Build config is set temporarily and then removed before calling runqemu. I'll send a separate patch to master-next to reduce spam. aarch64 host uses "-cpu host" with qemu while x86_64 sets the CPU variant explicitly to "-cpu cortex-a76". I can't see from build logs which CPU variant the host really is. There are a lot of CPU variants in aarch64 world and I don't think they are all compatible, or detect CPU features at runtime which can impact things like firmware code badly. I don't know how to fix this. Cheers, -Mikko
