[Qemu-devel] [PATCH 39/39] qemu-iotests: add 036 autoclear feature bit test |
Date: |
Fri, 15 Jun 2012 15:33:39 +0200 |
From: Stefan Hajnoczi <address@hidden>
This new test validates the autoclear feature bit behavior. When QEMU
opens a qcow2v3 image file with an unknown autoclear feature bit the bit
should be cleared in the image file header.
