Virtual Machine Live Migration Overview | Microsoft Learn
A live migration is deterministic, which means that the administrator, or script, that initiates the live migration determines which computer is used as the destination for the live migration. The guest operating system of the migrating virtual machine is not aware that the migration is happening, so no special configuration for the guest operating system is needed.

Run a live migration in the VMM fabric | Microsoft Learn
Live migration with shared storage. When you migrate a VM between clusters, note that the VM temporarily loses its high availability status. Therefore, a host failure during the migration causes the virtual machine to become unavailable. For live migration with shared storage, you must use SMB 3.0 file shares as the storage location. Because the storage does not have to be migrated, the time in which high availability status cannot be guaranteed is very short.

Virtual Machine Storage Migration Overview | Microsoft Learn
The most common reason for moving a virtual machine’s storage is to update the physical storage that is available to Hyper-V. You can also move virtual machine storage between physical storage devices, at run time, to respond to reduced performance that results from bottlenecks in the storage throughput. Key benefits

Hyper -V Live Migration, Storage Live Migration, Shared Nothing Live …
Difference between Storage Migration and Shared Nothing Live Migration. Storage Live Migration – provides the ability to move virtual machine’s storage from one diskt to another while VM is running with no loss of application downtime. Shared Nothing Live Migration – provides the ability to move virtual machine from one host to another over just a network cable. From Windows Server 2012 R2, when we enable Live Migration on a Hyper-V host we will be able to use additional features in …

Live Migration and Why It’s Important for VMware Cloud Partners
Live Migration And Why It’s Important For VMware Cloud Partners When moving VMware virtual machines to the cloud, the sure-fire way to migrate the VMs and their data completely is to simply stop the VMs, copy their components (OVF files) and assemble them into an Open Virtual Appliance (OVA).

KVM virtual machine live migration – Vinchin Backup
Try to use a network shared storage system on the source host and the destination host to save the client disk image. For example: NFS, ISCSI, Glusterfs, etc. In order to improve the success rate of dynamic migration, try to perform dynamic migration on hosts with the same type of CPU. Although KVM dynamic migration also supports migration from …

Migrate a Virtual Machine to New Storage – VMware
vCenter Server moves the virtual machine to the new storage location. Names of migrated virtual machine files on the destination datastore match the inventory name of the virtual machine. Event messages appear in the Events tab. The data displayed on the Summary tab shows the status and state throughout the migration. If errors occur during migration, the virtual machines revert to their original states and locations.

Libvirt Live Migrations Without Shared Storage
Counter to popular believe, you don’t need shared storage for libvirt live migrations. It works just fine with both lvm as well as qcow2 backed VMs. Let’s bootstrap libvirt on a fresh debian 10 (buster) machine, so we are on the same page: # First set up ssh key based authentication for your user. This is left as an exercise to the reader.
