How is load balancing implemented?

Sheepdog uses consistent hashing to decide where objects store; I/O load is balanced across the nodes. When a new node is added or the existing node is removed, the hash table changes and the data are automatically and transparently moved over nodes. We plan to implement a mechanism to distribute the data not randomly but intelligently; we could use machine load, the locations of VMs, free disk space information, etc.
