[libvirt] [PATCH] qemu: blockjob: Reset disk source index after pivot
by Peter Krempa 07 Dec '17

07 Dec '17

Since we are re-detecting the backing chain after pivoting to the active block commit target (or block copy target) the disk index needs to be reset to 0. This is necessary since we move a member of the backing chain to disk->src but clear indexes only starting from disk->src->backingStore. The freshly detected images have indexes starting from 1, but since we've pivoted into an image which was previously a backing store it would have a non-0 index. The lookup function would then return the top of the chain for queries like 'vda[1]' instead of the first backing store. This problem will not be present once we keep the disk indexes stable.
