Overview of a warm migration

The Logical Domains Manager on the source system accepts the request to migrate a domain and establishes a secure network connection with the Logical Domains Manager running on the target system. Once this connection has been established, the migration occurs.

The migration operation occurs in the following phases:

Phase 1

After connecting with the Logical Domains Manager running in the target host, information about the source system and domain are transferred to the target host. The Logical Domains Manager on the target host uses this information to perform a series of checks to determine whether a migration is possible. The checks differ depending on the state of the source domain. For example, if the source domain is active the Logical Domains Manger performs a different set of checks than if the domain is bound or inactive.

Phase 2

When all checks in Phase 1 have passed, the source and target systems prepare for the migration. The Logical Domains Manager on the source suspends and the source domain. On the target system, the Logical Domains Manager creates a domain to receive the source domain.

Phase 3

For an active domain, the next phase is to transfer all the runtime state information for the domain to the target. The Logical Domains Manager retrieves this information from the hypervisor. On the target, the Logical Domains Manager installs the state information in the hypervisor.

Phase 4

Handoff - after all state information is transferred, the handoff occurs when the target domain resumes execution (if the source was active). The Logical Domain Manager on the source destroys the source domain. From this point on, the target domain is the sole version of the domain running.
