Please squash this into the commit message when merging: The CD-ROM raw char device bypasses the host page cache and therefore has alignment requirements. Alignment probing is necessary so only use the raw char device if BDRV_O_NOCACHE is set. This patch fixes -cdrom /dev/cdrom on Mac OS X hosts, where bdrv_read() used to fail due to misaligned requests during image format probing. Reviewed-by: Stefan Hajnoczi <stefa...@redhat.com>
