I too have the same problems. Using ASUS P6T and Debian Lenny. I played around with it for weeks and just could not get it to work, here is my original post on the issue. http://www.nabble.com/ASUS-p6t,-i7-920,--vt-d-broken.....-td21624614.html I've given up for the moment...... Hi Steve,I'm also having a problem with the Asus P6T, but since I'm using Xen-unstable I'm not sure if this is the same problem than you have. Have a look at the "VT-D RMRR is incorrect" thread initially started by Yoshiharo Mori: It looks like the ACPI-DMAR tables are broken on some (Supermicro, Asus) X58 boards. This is a problem for Xen-unstable, disabling VT-d.I already opened a case with Asus but they are telling me that Linux is not officially supported. I'll continue to chase them as VT-d is (at least in theory) platform independent but it might help if others also open cases about this! Unfortunately I can't go back to Xen-stable for now to test if this is the same issue as I'm running on a paravirt_ops kernel that requires Xen-unstable (or at least heavy patching for 3.3). Btw, just looked at your other post again, the iommu=1 needs to go on the xen line and the pciback stuff on the line together with the linux kernel... and again, VMX (aka VT) has nothing to do with VT-d...
