Yes, except that it should actually work ;) It doesn't for me (Fedora 8 again). Grab xenner 0.9 (just uploaded), edit blkbackd.c and flip the BATCH_MAPS from 0 to 1, compile, run, see it not work. With BATCH_MAPS being 0 blkbackd works nicely as blktap/tapdisk drop-in replacement. cheers, Gerd _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linux-foundation.org/mailman/listinfo/virtualization
