So, i'm either stupid or my motherboard is incompatible , i sure hope it's not the motherboard...

 

after being completely unsuccessful with xen passthrough, and reading the release notes abot kvn in the b15 release, i updated to it and later to rc3, hoping for better luck, but my devices do not appear in the drop-down menu - only vnc.

 

my motherboard is Asus P5K-E http://www.asus.com/Motherboards/P5KEWIFIAP/overview/

it supposedly supports vt technology, and is enabled in the BIOS (appars as Vanderpool technology, under CPU features in BIOS).

i have 2 graphics boards installed, in the first x16 pci-e slot nVidia geforce 8400 gs, and in the second x16 slot a Sapphire radeon r9-285.

 

please help!

I think that you have Intel Vt-x not Intel Vt-d.

 

You need Vt-d to get passthrough to work.

 

It's a common cause of confusion with this sort of thing and as far as I'm aware you wouldn't be able to passthrough in Xen either.

 

 

Well, that clears that up... thanks. i guess my dream of making an all in one fileserver/desktop machine will have to wait
