Feature Specifications

Storage motion operations can only carried out by a CloudStack root administrator. Summary of the operations that storage motion will allow on Hyper-V

• Scenatio 1: Live migrating volume of a virtual machine. Virtual machine stays running on the same host.
  
  • A volume deployed on a local storage cannot be migrated to another storage pool. The volume has been created with a 'Disk Offering' as local. It can only reside on a local storage pool. Since the volume is attached to a running vm and is on a local storage it cannot be live migrated to another local storage pool on another host.
• Live migrating a virtual machine with its volumes to another host and storage pool
