[Qemu-devel] [PATCH 3/3] iotests: Test case for drive-mirror with unalig


From: Fam Zheng
Subject: [Qemu-devel] [PATCH 3/3] iotests: Test case for drive-mirror with unaligned image size
Date: Tue, 19 Apr 2016 18:09:09 +0800

This is the regression test for the virtual size mismatch issue between
target and source images.
