From 58226634c4b02af7b10862f7fbd3610a344bfb7f Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Thu, 30 Apr 2020 16:27:53 +0200 Subject: backup: Improve error for bdrv_getlength() failure bdrv_get_device_name() will be an empty string with modern management tools that don't use -drive. Use bdrv_get_device_or_node_name() instead so that the node name is used if the BlockBackend is anonymous. While at it, start with upper case to make the message consistent with the rest of the function.
