Virtual Machine
Migration
Migration is the process of moving a virtual
machine from one host or storage location to another. Copying a virtual machine
creates a new virtual machine. It is not a form of migration. vSphere supports
the following migration types:
Migration Type
| Description
|
|---|---|
Cold migration
| Moves a powered-off
virtual machine to a new host. Optionally, you can relocate configuration and
disk files to new storage locations.
|
Migration of a
suspended virtual machine
| Moves a suspended
virtual machine to a new host. Optionally, you can relocate configuration and
disk files to new storage location.
|
Migration with vMotion
| Moves a powered-on
virtual machine to a new host. Migration with vMotion allows you to move a
virtual machine to a new host without interruption in the availability of the
virtual machine.
|
Migration with Storage
vMotion
| Moves the virtual disks
or configuration file of a powered-on virtual machine to a new datastore.
Migration with Storage vMotion allows you to move a virtual machine’s storage
without interruption in the availability of the virtual machine.
|
Migration of a suspended virtual machine and
migration with vMotion are both sometimes called hot migration, because they
allow migration of a virtual machine without powering it off.
You can move virtual machines manually or set up
a scheduled task to perform the cold migration.
