| H A D | 030 | efcc7a23 Tue May 08 14:51:58 GMT 2012 Paolo Bonzini <pbonzini@redhat.com> stream: do not copy unallocated sectors from the base
Unallocated sectors should really never be accessed by the guest,
so there's no need to copy them during the streaming process.
If they are read by the guest during streaming, guest-initiated
copy-on-read will copy them (we're in the base == NULL case, which
enables copy on read). If they are read after we disconnect the
image from the base, they will read as zeroes anyway.
