Hyper-V enables you to both move a VM and to move the storage for a VM to a new location. Moving a VM and moving a VM's storage are two important features you can use to manage your Hyper-V hosts.
With live migration, you can move a Hyper-V VM to a different VM host with no downtime. This works best when the VM is held on shared storage (via a fiber channel SAN, iSCSI, or SMB). You can also move a VM's storage (that is any VHD/VHDX associated with the VM) to a different location. You can also combine these and move a VM supported by local storage to another Hyper-V host (moving both the VM and the underlying storage).
In this recipe, you first move the storage for the VM1
VM. You created this VM in the Creating a virtual machine recipe and stored the VM configuration and the VM's VHD on the H:
drive. To move the storage, you create a new SMB share and then move the VM's storage to the new SMB share.
In the second part of this recipe, you do a live migration...
