[Xen-users] Xen 4.1.2 HT disaware (?)

Hi there!
I just fresh-installed Xen on new server, Xeon E5-2620, and noticed
following thing:

node1~ #  dmidecode L | grep -A2 "Core Count"
        Core Count: 6
        Core Enabled: 6
        Thread Count: 12

So, HyperThreading is actually enabled, but Xen shows (and operates)
only phisycal cores.

As far, as I remember, when I used Xen on hexacore i7 some time ago,
there was 12 cores to operate.
So, is it normal behaviour for now, and cant it be fixed somehow?
And, also, maybe I need to paste something else?
