Hi Philippe, Markus,

I encountered an issue where device-introspect-test.c gets me a qemu-system-aarch64 launched as:

./qemu-system-aarch64 -qtest ... -display none -nodefaults -machine none -accel qtest

and results in an attempt to create a device "ast2400-a1",
which tries to create a arm926-arm-cpu, which fails because it is a "TCG" cpu, that is not built in my kvm-only build.

Any ideas why this happens?

Thanks,

Claudio
