Storage motion changes:
1. Fixed the code for migration of VM with its volumes across cluster.
2. Made changes to update the volume paths after migration across cluster.
3. Fixed the code to pick up the volume/pool mapping passed when migrating across cluster.
4. Resolved an issue where storage xenmotion of 2nd VM created from the same template to a host was failing with duplicate_vm exception. Made changes to remove the mac_seed key value pair from other_config when vms are created. This is was storage motion to fail.
