Hello,

I'm also seeing this. I have DQ35JO motherboard and a Q6600 processor. I have the latest 933 bios for my motherboard. It hangs for me at "Brought up 4 CPUs." I've gone through many many different distros and can't find a solution. I've also tried xen-unstable, but then vt-d does not get enabled. I get "I/O Virtualisation disabled."

Any ideas?

Thanks,

-Bryan

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

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
