[ovirt-users] Import VM from ovirt-exported ova

Hello, i installed a new oVirt 4.3.4 from scratch and am attempting to restore the VMs which ran perfectly fine on my last oVirt 4.2.8, where i exported the VM to the export domain and also as an OVA file. Importing the export domain fails, which i plan to debug later. But importing the OVA file via the Administration Portal also fails with Error ID: 1153 Message: Failed to import the VM to Data Center, Cluster. The VM name is still recognised by the import routine, which tells me the file is readable... Now my questions: Is there any option to try the same from CLI, hoping to get better clues for what is going on? Are there specific log options which could give some clues? Would it be better in general to import the VM from an export-storage domain instead of using a OVA export? Any hint would highly appreciated. Best
