Subject: [Qemu-devel] [PATCH 0/2] qemu-img convert: ignore read errors
Date: Tue,  9 Apr 2019 17:56:30 +0300	[thread overview]
Message-ID: <1554821792-968307-1-git-send-email-andrey.shinkevich@virtuozzo.com> (raw)

The 'qemu-img convert' new command option 'force read' with the key '-R'
allows converting a damaged image to get all the available information
in case of the read errors. The program reports read errors and continue
the image conversion. The users should keep in their minds that the
resulting image is inconsistent.
