The libxl driver has basic support for VIR_MIGRATE_CHANGE_PROTECTION by starting and stopping modify jobs in the begin/confirm and prepare/finish phases of migration, but it doesn't advertise that support. This can result in unterminated jobs because the migration logic skips phases of migration when the VIR_MIGRATE_CHANGE_PROTECTION feature is absent. Ensure jobs are terminated properly by advertising support for VIR_MIGRATE_CHANGE_PROTECTION. Signed-off-by: Jim Fehlig <jfehlig@suse.com> Reviewed-by: Daniel P. Berrangé <berrange@redhat.com>
