Domain migration enables you to migrate a guest domain from one host machine to another host machine. The machine on which the migration is initiated is the source machine. The machine to which the domain is migrated is the target machine.
While a migration operation is in progress, the domain to be migrated is transferred from the source machine to the migrated domain on the target machine.
The Oracle VM Server for SPARC 2.1 release introduces live migration, which provides performance improvements that enable an active domain to be migrated while it continues to run. In addition to live migration, you can migrate bound or inactive domains, which is called cold migration.
You can use domain migration to perform tasks such as the following:
Balancing the load between machines
Performing hardware maintenance while a guest domain continues to run
