[PULL 02/12] dump: Improve error message when target doesn't support memory dump

Posted by Markus Armbruster 2 years, 11 months ago

The QERR_ macros are leftovers from the days of "rich" error objects.
We've been trying to reduce their remaining use.

Get rid of a use of QERR_UNSUPPORTED, and improve the rather vague
error message

    (qemu) dump-guest-memory mumble
    Error: this feature or command is not currently supported

to

    Error: dumping guest memory is not supported on this target
