Booting u-boot on qemu with kvm is currently hanging on aarch64 build host. Root cause is in u-boot and CONFIG_BLOBLIST can be disabled as a workaround. To reproduce, build on kvm enabled host where "kvm-ok" succeeds. For example genericarm64 machine and core-image-base should then boot with: $ runqemu slirp nographic novga snapshot kvm On qemuarm64, default kvm setup will boot directly to kernel and is not affected by this. If build enables u-boot as bios then the same issue happens. Without this config workaround, the boot hangs without any messages in qemu output but ctrl-a-c to qemu console can shutdown the emulated machine. This seems to have regressed after u-boot 2025.04 update. KVM boot can be detected from speed, for example genericarm64 boots in 550 ms with KVM and without in over 5 seconds.
