Re: ESXi 4.1 on Intel DQ67-EP
Yes, vt-d and vt-x are supported on Intel DQ67-xx series.
Be sure to get a CPU that supports vt-d too. (that is Core i5 or i7, i3 won't support this feature. note that i5 and i7 "K" series won't support vt-d either)
vmDirectPath with a Perc5i worked too, but this card does not seem to support passthrough (disks are seen, but unusable)
I've heard of some builds with DQ67SW and a Perc6i that work though...
Will probably try to passthrough the graphic controller someday, see if it can be useful
Intel vPro is quite a great feature too (gives you "ILO card" like functionnality on a desktop board... great!)
Only drawback is the unsupported on-board NIC :/
I'm thinking of upgrading to a DQ67SW though... (more DIMM slots, more PCI slots)
