Hello all,

please tell me, how can I be sure that my Xen installation is built with Intel VT-d support?

Something like
xm info | grep -i KEY-REGULAR-EXPRESSION
xm dmesg | grep -i KEY-REGULAR-EXPRESSION


What line I should look for?

And if it's really built with it, how can I be sure, that Xen has successfully initialized VT-d hardware?

As far as I know, xm dmesg should show this, but I didn't find any vt-d enabled hardware by now. If you're hardware supports vt-d could you please post the model and vendor?



I have read [1] and the lists archives and found no answers for my question.



Thank you in advance.
