As I said before, we should remove the previous current VDI.

We can do the same thing by deleting and recreating the vdi. The benefits of the 'vdi reset' command is only performance? If so, to be honest, I don't like to merge it. I don't understand why we need a performance for reseting cloned vdis. Thanks, Kazutaka -- sheepdog mailing list sheepdog@lists.wpkg.org http://lists.wpkg.org/mailman/listinfo/sheepdog
