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,
