I haven't tried 4.5 - I last used 4.3 and that worked for me.
I have now switched to KVM (as of last weekend) due to Nvidia's
abandonment of Xen dom0 support.

May I ask what you mean with "Nvidia's abandonment of Xen dom0 support",

They appear to have stopped even trying to make the recent binary
drivers work in dom0. I mentioned this before last year, but the
relevant discussion on the Nvidia forum is here:


and why/how this affect passthrough?

It doesn't affect passthrough - it merely means that Nvidia binary
drivers don't work for me in dom0 on newer GPUs, and I wanted to
switch to a GT 630 (single slot, fanless) for my dom0.
