&gt; How&#x27;s much of a performance hit do you get running a VM with vtx and vtd versus running windows bare metal?<p>I&#x27;ve seen research that shows the GPU being 98-99% when using QEMU&#x2F;KVM.  I haven&#x27;t used the system long enough to accurately quantify my personal experience.<p>&gt; Is it as simple as it seems?<p>For me getting the GPU working was the easiest part.  It worked on the first try.  The hardest part was finding good docs (Arch wiki &amp; VFIO blog), trying to understand their little ecosystem, and finding the right compatible parts (hint: besides the CPU, it&#x27;s really easy).  I&#x27;d never used QEMU&#x2F;KVM before (I used VirtualBox previously) so that was a big learning curve.  It seems like things have matured quite a bit since the VFIO blog wrote its articles, as a number of things had changed and become easier.
