Thread-topic:	Xen-3.2.1 VT-d Support (NOT SURE WHETHER IT'S A BUG OR ...)

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...

=========================

My chipset DQ35 series is having VT-d support and is enabled in the BIOS as well.

My domain0 is CentOS-5.2(2.6.18.8-xen).

Is this a possible bug or some thing else??

Any Idea??

Thx,

Venkat
