When selecting an incorrect CPU, there is a mismatch between the CPU name provided and the one displayed (which is some QEMU internal name):
$ qemu-system-aarch64 -M virt -cpu cortex-a8 qemu-system-aarch64: mach-virt: CPU type cortex-a8-arm-cpu not supported Strip the suffix to display the correct CPU name: $ qemu-system-aarch64 -M virt -cpu cortex-a8 qemu-system-aarch64: mach-virt: CPU type cortex-a8-arm Signed-off-by: Philippe Mathieu-Daudé <[email protected]> --- hw/arm/virt.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/hw/arm/virt.c b/hw/arm/virt.c index 399da734548..7802d3a66e8 100644 --- a/hw/arm/virt.c +++ b/hw/arm/virt.c @@ -1829,7 +1829,10 @@ static void machvirt_init(MachineState *machine) finalize_gic_version(vms); if (!cpu_type_valid(machine->cpu_type)) { - error_report("mach-virt: CPU type %s not supported", machine->cpu_type); + int len = strlen(machine->cpu_type) - strlen(ARM_CPU_TYPE_SUFFIX); + + error_report("mach-virt: CPU type %.*s not supported", + len, machine->cpu_type); exit(1); } -- 2.26.2
