SR-IOV Passthrought + +Definitions of SRIOV_Port are necessary if VDU supports SR-IOV.

Hugepages + +Definitions of mem_page_size as one property shall be added to +Properties and set the value to large if one VDU node supports +huagepages.

NUMA (CPU/Mem) + +Likewise, we shall add definitions of numa to +requested_additional_capabilities if we wand VUD nodes to support +NUMA.

Hyper-Theading + +Definitions of Hyper-Theading are necessary as one of +requested_additional_capabilities of one VUD node if that node +supports Hyper-Theading.
