Nehalems do have VT-d, but they have dedicated chip with north bridge still, CPU only provided memory controller. So VT-d is the feature of the chipset, e.g. X58, not mentioning Xeon chipsets. On the other hand, VT-d support was relatively buggy, could it be that Xen kernel refuses to use it due to the problems ? > > > I think I have used Xen a bit older version on Debian some time back if Im not wrong, on the same hdw. > > See below. > > > >> But you need all boot log.
