[Qemu-devel] [PATCH] block: Adds mirroring tests for resized images |
Date: |
Fri, 25 Jan 2013 10:57:20 -0800 |
This test verifies two mirroring issues are fixed with resized images:
* sync='top' creates an image that is the proper size
* sync='full' doesn't cause an assertion failure and crash qemu

These are tests for my patches for the following bugs:
