Thread-topic:	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
