[Xen-devel] 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??

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.

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.
