Example 1 with MigrationOptions

use of com.cloud.storage.MigrationOptions in project cloudstack by apache.

the class StorageSystemDataMotionStrategy method createLinkedCloneMigrationOptions.

/**
 * Return expected MigrationOptions for a linked clone volume live storage migration
 */

    String backingFile = ref != null ? ref.getInstallPath() : srcVolumeBackingFile;
    return new MigrationOptions(srcPoolUuid, srcPoolType, backingFile, updateBackingFileReference);
}

Example 2 with MigrationOptions

use of com.cloud.storage.MigrationOptions in project cloudstack by apache.

the class StorageSystemDataMotionStrategy method setVolumeMigrationOptions.

/**
 * Prepare hosts for KVM live storage migration depending on volume type by setting MigrationOptions on destination volume:
 * - Linked clones (backing file on disk): Decide if template (backing file) should be copied to destination storage prior disk creation
 * - Full clones (no backing file): Take snapshot of the VM prior disk creation
 * Return this information
