OK, here we go.  Understand my XML is a little in pieces right now, as
i am trying to re-add the
<hyperv> settings and the one under <clock offset='localtime'>.  In
order to get the VM to boot i
had to remove the Nvidia card.  I first tried putting back all 3
hyperv settings and the clock setting,
but that didnt work.  So then i took out the clock setting and tried,
still not luck.  The last thing i
tried was just the clock setting and took out the 3 hyperv.  Still
nothing.  All this without the video
card in.

   * Passing the Nvidia card because its a MUCH better gaming card. The 2
pci-stub devices are 2 Intel USB controllers.  Those are working fine
in the VM.  For some reason the USB controllers would not work with
vfio-pci, but worked fine with pci-stub*

You shouldn't need to bind vfio-pci or pci-stub to your USB controllers at boot, those can be detached and reattached dynamically at runtime.

Your config looks pretty good, aside from the fact that you still have a virtual VGA adapter and that I'm not seeing your guest GPU (02:00.00) in your VM config. You're saying your VM can't boot when it's attached, do you mean that you're actually just getting an Error 43 or tht your GPU is simply not outputting anything?

I have tried putting each of the below settings back into the XML, one
at a time.  Any one of these lines will cause the VM to fail to boot,
and then reboot in windows repair mode.  Not sure what i can do about
that.  Again, i don't use “-cpu
host,kvm=off” anywhere.  I was never really clear on where to put that
setting at anyway.   Does anyone think i should be using it?
Don't mind those command line arguments, those are if you're using qemu without libvirt. You're already passing them to qemu by having <kvm><hidden state='on'/></kvm> in your guest config.

My next problem i want to tackle is my audio issues.  I am using the
HDMI audio from the Nvidia card.  It will sometimes cut out for a
split second for no reason, maybe once every 5 to 10 seconds.  Also
sometimes during games I will hear a quick "tearing" noise.
You'll want to enable MSI interrupts <http://vfio.blogspot.ca/2014/09/vfio-interrupts-and-how-to-coax-windows.html> for that. The Arch wiki article doesn't mention it yet (I was planning to add it sometime soon), but it's a requirement to get HDMI audio to work properly.
