I really appreciate it.<br>
<br>
So, to summarize and make sure I have condensed all this info properly,<br>
the consensus seems to be that:<br>
<br>
1. Current Skylake CPUs are a bad choice for vfio builds (because of a<br>
lack of ACS).<br>
2. Xeon E5 CPUs are good. E3 and Core iX CPUs are bad for vfio<br>
(because of a lack of ACS).<br>
3. Look for motherboards that explicitly list VT-d as a feature. ASUS<br>
boards seem to be wonky. People seem to have good success with ASRock<br>
boards.<br>
4. Configurations that rely on the ACS override patch may act weird,<br>
and are less likely to be supported. Which makes sense given the<br>
nature of the patch.<br>
<br>
As I was researching a build to leverage vfio, I did read AW's blog<br>
posts, but had thought "Xeon? I'm not made of money!" After seeing it<br>
pushed more on this list, I did more research and found that some of the<br>
"entry-level" Xeons (specifically the E5-1620 V3) are very much within<br>
the realm of regular people.<br>
<br>
Additionally, from those links to the HW lists, it seems that the an<br>
ASRock (in my case, a X99 Extreme4 since its cheaper than the 6, thanks<br>
for the pointer Nick) paired with a Xeon E5-1620 V3 is a practical and<br>
cost effective solution.<br>
<br>
Thanks again!<br>
