From 0b1847bbc2b4f50e7497cb05c4540bf7b016c9c6 Mon Sep 17 00:00:00 2001 From: Stefano Garzarella Date: Mon, 15 Jul 2019 15:28:44 +0200 Subject: [PATCH] gluster: fix .bdrv_reopen_prepare when backing file is a JSON object When the backing_file is specified as a JSON object, the qemu_gluster_reopen_prepare() fails with this message: invalid URI json:{"server.0.host": ...} In this case, we should call qemu_gluster_init() using the QDict 'state->options' that contains the JSON parameters already parsed.
