[Engine-devel] multi-domain types in one storagepool

Hi, all After taking a look at Ovirt-engine, I happen to notice that for one DC(storage pool), only one type of data domain can be attached. As far as I know, from VDSM side, different data storages can be managed by one storagepool. So, why is there such limitation? is it possible to remove such rule from front-end? Maybe there are some reasons I don't know support this rule, hope someone can show me some light. thanks Joseph
