Philipp Schuster d90f852ddf virtio-devices: block: add helpful message on failed sector 0 write
We ran the Microsoft Windows installer in CHV (via network + VNC) and
the installation always failed when the installer wanted to write the
partition table. Since recently, for very good reason, sector 0 writes
are disabled if the image type is not set explicitly and only
implicitly auto-detected as raw [0].

To ease troubleshooting, I've added a descriptive log message. It is a
little spammy, but it is what is required to help users to troubleshoot.
