[ovirt-users] OVF_STORE update error

hi. I use automatic translation, not English as my main language. Please note that this is a difficult expression to understand. I have an NFS storage domain that I used with ovirt 4.4 and I imported it with oracle linux virtualization manager 4.3. As a result, OVF_STORE fails to update. Failed to update VMs/Templates OVF data for Storage Domain [Domain Name] in Data Center [DC Name]. Failed to update OVF disks [OVF_STORE1_diskID],[OVF_STORE2_diskID], OVF data ins't updated on those OVF stores (Data Center [DC Name], Storage Domain [Domain Name]). In addition, there was the following log. [org.ovirt.engine.core.bll.storage.ovfstore.UploadStreamCommant] (EE-ManagedThreadFactory-engineScheduled-Thread-100) [4859c0db] Validation of action 'UploadStream' failed for user SYSTEM. Reasons: VAR__TYPE__STORAGE__DOMAIN,ACTION_TYPE_FAILED_DISK_VOLUME_TYPE_UNSUPPORTED,$volumeTypeSparse,$supportedVolumeTypes Preallocated With ovirt 4.4, OVF STORE is created with thin provisioning. With olvm4.3, I think the problem is that OVF_STORE is created in Preallocated. Is there a way to fix it while the virtual machine is still running? Thank you.
