> The storage code right now restricts usage of multiple image store providers in the same zone. But it restricts this even when the image store may be in a different zone/region.
> From StorageManagerImpl.java:
>         // check if we have already image stores from other different providers,
>         // we currently are not supporting image stores from different
>         // providers co-existing
>         List<ImageStoreVO> imageStores = _imageStoreDao.listImageStores();
>         for (ImageStoreVO store : imageStores) {
>             if (!store.getProviderName().equalsIgnoreCase(providerName)) {
>                 throw new InvalidParameterValueException("You can only add new image stores from the same provider " + store.getProviderName()
>                         + " already added");
>             }
>         }
> search criteria lists all add images stores:
> @Override
>     public List<ImageStoreVO> listImageStores() {
>         SearchCriteria<ImageStoreVO> sc = createSearchCriteria();
>         sc.addAnd("role", SearchCriteria.Op.EQ, DataStoreRole.Image);
>         return listBy(sc);
>     }
