HD4000 graphics is provided by the CPU and it works with primary VGA
passthrough with the xm toolstack running Wheezy stock linux kernel an
4.1.x hypervisor.

Really? Why wouldn't it work for secondary passthrough?

I'd suspect that it does work for secondary passthrough.  I'm under the impression that working primary passthrough devices are a subset of working secondary passthrough devices.  I'd love to know if that's not the case, though!

I have one of those in my microserver. It's not really up to the task of gaming
(hell, it isn't even up to the task of HD video decoding and
scaling it down to 1366x768), but it can take 16GB of RAM, so makes
for a reasonably neat, dirt cheap, low-performance VM testing machine.

FLR- in my personnal experience doesnt mean much.

You have seen the mythical item that is a GPU with FLR? If you
haven't I'm not sure how you can make a reasonable experience
based comparison.

I've managed HD4000 with VGA passthrough. VGA passthrough implies that HD4000 was the primary display device.

Honestly don't recall using PCI passthrough on the HD4000 because as soon as I got discrete graphics cards I've been using the HD4000 for dom0.
