OVM 3.0.3 import VirtualBox OVM Manager 3.0.3 OVA template

Question

VirtualBox Template for Oracle VM Manager 3.0.3,
http://www.oracle.com/technetwork/server-storage/vm/template-1482544.html
The OVM 3.0.3 host should be configured with enough space to accommodate import of OVA template. In
this case 36G was allocated for "sda",
