I have found that I can import thin-provisioned VMs from VMWare ESXi into an oVirt (3.6 Hosted-Engine) iSCSI  storage domain as thin-provisioned VMs by doing the following :

1 . Import the thin-provisioned VMWare VM into an NFS storage domain.

2.  Export the thin-provisioned VM from the NFS storage domain.into the oVirt Export domain.

3.  Import the thin-provisioned VM into an iSCSI Storage Domain from the oVirt Export domain

Is there a simpler way to do this using the 3.6 Import capability ? Or, do we need to follow the above procedure to get VMs into oVirt from VMWare as thin-provisioned VMs ?

Thank You For Your Help !
