From 248337e178fbcf1c20132d4f3d1033cb0dde7638 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Mon, 9 Feb 2015 11:49:08 +0100 Subject: vhost-scsi: Improve error reporting for invalid vhostfd We get two error messages: one from monitor_handle_fd_param2(), and another one from vhost_scsi_realize(). The second one gets suppressed in QMP context. That's because monitor_handle_fd_param() calls qerror_report_err(). Calling qerror_report_err() is always inappropriate in realize methods, because it doesn't return the Error object. It either reports the error to stderr or the human monitor, or it stores it in the QMP monitor, where it makes the QMP command fail even when the realize method ignores the error and succeeds. Fortunately, vhost_scsi_realize() doesn't do that. Fix by switching to monitor_handle_fd_param2().
