Xen users - Aug 2008 - Xen-3.2.1 VT-d support

After building Xen-3.2.1 I could successfully boot into it if I avoid giving
vtd=1 as the boot parameter.
If I pass vtd=1 as the boot parameter to xen, the system hangs while booting.
The system hangs after the following messages
===========================Boot messages
[XEN].....
[Xen] Brought up 2 CPUs...
========================After sometime an error message is popped related to
"DMAR".

Is it due to improper build of xen-3.2.1.Any idea??

Thx,
Venkat

Obvious question first, have you got a VT-d capable CPU and 
motherboard/BIOS?

Venkat,

Which CPU and motherboard/chipset are you using?  Have you verified
that:

#1. You have an Intel VT-d capable motherboard?

#2. Intel VT-d is turned on in the BIOS?

Cheers,

Daniel
