From 82f20e8547ce665e9bb23fdb55374840b846c143 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Tue, 28 Mar 2017 10:56:03 +0200 Subject: rbd: Don't accept -drive driver=rbd, keyvalue-pairs=... The way we communicate extra key-value pairs from qemu_rbd_parse_filename() to qemu_rbd_open() exposes option parameter "keyvalue-pairs" on the command line. It's not wanted there. Hack: rename the parameter to "=keyvalue-pairs" to make it inaccessible.
