[Xen-users] I/O virtualisation disabled - ACPI issue?

[Jami Bradley <bradleyfamily.jami@xxxxxxxxx>]

I just started using Xen and am trying to come up to speed.  I am trying to configure a desktop PC to boot Xen, then passthrough VGA, Keyboard, and Mouse to a VM for development.  I have a Win7 DomU working beautifully without the passthrough, so I have the basics working.

Here is my configuration (please let me know if I missed something important):

ASUS P9X79 Pro motherboard, current BIOS, with VT-D enabled.

Intel I7-4930K processor

I installed CentOS 6.5 minimal for Dom0, plus a couple packages to get things working (e.g., Perl).  I have xend turned off and I am trying to do everything using the XL toolkit.

I have installed Xen 4.2.3 stable and have built and installed the current head from GIT (post 4.3.1) with identical results.

After some debugging, I believe it is failing to parse the ACPI table (acpi_drhd_units is empty in intel_vtd_setup) and disabling IOMMU.

Any tips on how to proceed?

Thanks!
