You mean I cannot have QEMU attach all clusters by default?

So far the behavior that we had was to see all the CPUs without asking
explicitly.
I want to go back to that behavior because the current situation is a
huge drawback for our users.

The commands:
        target extended-remote :1234
        add-inferior
        inferior 2
        attach 2
        set schedule-multiple
        info threads

Do not work for me, "attach 2" in GDB asks me to kill the debugged program.

Thanks for your help,
