Re: [Xen-devel] No VT-d with Xen 3.3/3.4rc3 on Intel-Board DQ45CB

Got SOL workin'.

Grub looks like this:
title Xen 3.4.0-rc3-pre / Debian GNU/Linux, kernel 2.6.18.8- xen 
root            (hd0,0)
kernel /xen-3.4.0-rc3-pre.gz console=com1 com1=115200,8n1,0xe1c0,0 module /vmlinuz-2.6.18.8-xen root=/dev/mapper/raidvg-lv-- dom0--root ro console=tty0 
module          /initrd.img-2.6.18.8-xen
I'm using amtterm on the client machine. It's in Debian testing currently, but can easily be downloaded and installed via dpkg -i in Ubuntu 8.04 LTS. 

I connected to AMT with

amtterm -u admin -p supersecretpassword 10.11.1.31

As soon as I rebooted the AMT computer the client was receiving data.
Attached is the output of booting with iommu=1. For reasons unknown, the lines I quoted as an example a couple of mails ago aren't in there.
