To my best knowledge they shouldn't use swiotlb if you give the dom0 4GiB+
of RAM. I posted the exact same problem before and that was the recommendation
I got. It works.

I'm not keen on letting dom0 take up so much memory :)
I'm giving swiotlb 256MB of memory (swiotlb=131072 on el6/7) and that resolved it for my configuration.
