Hello,

I've got a X9DR7-LN4F, Dual e5-2620, etc.

BIOS says VT-D and the like are enabled.

I'm trying to do pci passthrough so I can run VMWare on bare metal, then export my HBA's to a OI VM.

I spotted the following error in dmesg when I had VMWare installed.
0:00:00:04.621 cpu0:8192)IOMMUIntel: 5179: No DMAR ACPI location found

I am running a recent beta bios from SuperMicro to address issues I had having 2+Onboard HBA's in the system causing it to not boot (Would post, but failed scanning OPROMS)

I've seen a few users on the forum running this specific board, Have you had any luck running vmware and using vt-d on it?

I did search the VMWare forums, and came up with something about editing a vmware config file, and adding vhv_allowed = "TRUE" or something like that, tried that and no luck.

Ah, it seems that after toggling a bunch of BIOS options, it seems to work now.

Hooray?

Heh... there are option in BIOS that sometimes need to be set. Couldn't figure out why it wasn't working for you.
