Canceling a Migration in Progress

After a migration starts, the migration operation is terminated if the ldm command is interrupted by a KILL signal. When the migration operation is terminated, the migrated domain is destroyed, and the domain to be migrated is resumed if it was active. If the controlling shell of the ldm command is lost, the migration continues in the background.

A migration operation can also be canceled externally by using the ldm cancel-operation command. This command terminates the migration in progress, and the domain being migrated resumes as the active domain. The ldm cancel-operation command must be initiated from the source machine. On a given machine, any migration-related command affects the migration operation that was started from that machine. A target machine cannot control a migration operation.


Note - After a migration has been initiated, suspending the ldm process does not pause the operation. The operation is not paused because the Logical Domains Manager daemon (ldmd) on the source and target machines, and not the ldm process, affects the migration. The ldm process awaits a signal from ldmd that the migration has completed before returning.
