[Xen-users] RE: Successful PCIe Graphics VT-d Passthrough to Win32 DomU, Q35 chipset

["Peter J. van der Maas" <peter@xxxxxxxxx>]

I have been receiving quite a few e-mails regarding VT-d in particular since my posting.  I have not really played with much since accomplishing a proof-of-concept.  I am waiting for engineers at Intel, Citrix (Xen), etc. to get their sh!t together before even thinking of documenting or putting into production.  One of my biggest problems was waiting for Intel to make appropriate changes to the BIOS of the board I was working with.  Anyone that has been working with VT-d in particular can see that Intel is scared of the toothpaste they let out of the tube because of lost revenue in VM’s (initially).  Do you think they want you running X number VM’s on just 1 product?  Right.  Let them figure out a way to screw you on VT and charge per VM - then the technology will (maybe) work like we want.

 

To the die-hard nerds like myself dedicated to getting this to work, check your BIOS version and the build of Xen (anything like 3.3.x, 3.4.x, etc. will probably FAIL…use mecurial and get something new.  Read.  Study.  You will get there. The original post included my parameters.  If you have specifics, feel free to ask, but refrain from statements such as “I bought a PC.  Now what do I do?”.

 

The answer is out there.
