The s390-ipl device can not be created by the user, since it is meant only
|
|
|
9bac43 |
to be instantiated once internally to load the ROMs and kernel. If the user
|
|
|
9bac43 |
tries to do a "device_add s390-ipl" via the monitor later, QEMU aborts with
|
|
|
9bac43 |
a "ROM images must be loaded at startup" error message.
