From 21c7f3f74959f18c5feb9b44511cb1a965c25a36 Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Fri, 6 Feb 2015 16:06:18 -0500 Subject: iotests: Add test for drive-mirror with NBD target When the drive-mirror block job is completed, it will call bdrv_swap() on the source and the target BDS; this should obviously not result in a segmentation fault.
