Offloading techniques to assist a hypervisor with VM data migration between storage devices are disclosed. In an embodiment, a method to offload live data migration from hypervisors includes migrating snapshots from a source device to a destination device, where the snapshots are associated with a virtual machine (VM) being migrated from a source device to a destination device. The method includes requesting a hypervisor to take a hypervisor snapshot. The method includes taking a storage array-based snapshot after requesting the hypervisor to take the hypervisor snapshot, and requesting the hypervisor to migrate live data from the source device to the destination device including by using the hypervisor snapshot to offload hypervisor live data migration. Hypervisor offload can be performed for various hypervisors and protocols including vSphere Storage APIs Array Integration (VAAI) and Remote offloaded data transfer (ODX).

Hypervisor remote offload for VM data migration between storage devices

VM data migration between storage devices is disclosed. In an embodiment, a method of VM data migration includes determining snapshot data and live data corresponding to the VM based on a request to migrate a VM from a source device to a destination device. The method migrates the snapshot data from the source device to the destination device including by setting up a migration path and creating a migration configuration in the source device. The method requests a hypervisor to migrate the live data from the source device to the destination device. The method removes the migration path, the migration configuration, and snapshot data from the source device.
