The BIOS version I use may be not the exact one as yours. I mean I expect you're not using a very old BIOS. :-)
How about
trying the xen 3.2.2-rc2 and the latest xen-unstable first?
There are some
VT-d bug fixes between 3.2.1 (you're using it) and 3.2.2-rc2.
Thanks,

If you don’t mind can you send me the BIOS version you are using?
Thx,
Venkat

Hi Venkat,
Can you confirm you're using the latest BIOS? Can you try the xen 3.2.2-rc2 and the latest xen-unstable on the same host?
I have the similar host. Xen 3.2.2-rc2 and the latest xen-unstable both work well on it.
Thanks,

(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
