To say short VT is CPU virtualization and VT-d is I/O virtualization.
Take a look at the page [1] for more information.


Be means of VT-d you can try to make PCI-passthrough of some HW 
(e.g. network card) into HVM domain. 
This is impossible without VT-d (you can do PCI passthrough into
PV-domains only).
