From 75dfd402a734e8080fa77a1bcf60ecc46e0e6158 Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Thu, 23 Jun 2016 14:20:24 +0200 Subject: block: Accept node-name for blockdev-snapshot-internal-sync In order to remove the necessity to use BlockBackend names in the external API, we want to allow node-names everywhere. This converts blockdev-snapshot-internal-sync to accept a node-name without lifting the restriction that we're operating at a root node. In case of an invalid device name, the command returns the GenericError error class now instead of DeviceNotFound, because this is what qmp_get_root_bs() returns.
