convert HDD selection of new instance creation to user request. Before that, instance creation gets all images of all pools. If there is a problem with some pools other than default. It causes problem and sometimes it takes too long to opeen create instance page. With that extension getting volumes is up to request. Firs you must select pool then select volume. For now the create page opens instantly.
