Hi,
I am currently trying to figure out if my desktop machine (Dell XPS 8500) supports Intel's VT-d.
The processor is a Core i7 3770 and the chipset is a H77 PantherPoint.
I installed Xen 4.1 and did a
Now, the output is:
The VT-d related output confuses me. It says I/O virtualisation is enabled, however, DMA remapping is not enabled. DMA remapping is one essential feature of VT-d (which I need). Any idea how to enable this? I checked the BIOS and enabled "Intel Virtualization Technology".
Thanks for any help!
