Date: Thu, 4 Feb 2010 15:43:57 +0200 [thread overview]
Message-ID: <1265291041-31100-1-git-send-email-nsprei@redhat.com> (raw)
This is version 2. The change between previous patch (only 3/4) is the order of closing/re-opening the image.
The read-only changes broke qemu-img create with read-only base image
These changes fix it.
It also make things a little safer, opening the backing file for read-only,
upgrading to read-write only for commit, and back to read-only when done.
Naphtali Sprei (4):
Add open_flags to BlockDriverState Will be used later
qemu-img: Fix qemu-img can't create qcow image based on read-only
image
Block: readonly changes
Open backing file read-only also for snapshot mode
