 Within the Harvester context, volumes backed by the Longhorn V2 Data Engine must be added to virtual machines as extra disks. The boot disk of each virtual machine must still be added from an image that is backed by the Longhorn V1 Data Engine.
 
 Harvester is unable to live-migrate virtual machines with V2 volumes attached, which means those virtual machines will be shut down during Harvester cluster upgrades. Moreover, snapshots of V2 volumes cannot be created because snapshot and restoration functionality in Harvester relies on volume cloning.
