[Qemu-devel] [FOR 0.12 PATCH 02/18] monitor: do_cont(): Don't ask for passwords

[Markus Armbruster]

From: Luiz Capitulino <address@hidden>

The do_cont() function will ask the user to enter a password if a
device is encrypted.

This is invalid under QMP, so we raise a QERR_DEVICE_ENCRYPTED
error.
