Since that is a very common guest action on initial install of an OS into a blank disk, and also should NEVER match one of our probes (assuming we never add support for a file format that resembles an MBR master sector), it would be nice to ensure that our restrictions against writing to sector 0 only fire when actually hitting a colliding probe, and not for all writes. Likewise, maybe add a test for writing a sector of all 0 or all FF. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
