[Qemu-devel] [PATCH for-2.13 v5 04/11] hmp: disable monitor in preconfig state

[Igor Mammedov <imammedo@redhat.com>]

Ban it for now, if someone would need it to work early,
one would have to implement checks if HMP command is valid
at preconfig state.

v5:
  * add 'use QMP instead" to error message, suggesting user
    the right interface to use
v4:
  * v3 was only printing error but not preventing command execution,
    Fix it by returning after printing error message.
