Did you check whether the cards include UEFI support in the ROM?  It's sad
that vendors are shipping cards these days without it, but that's the first
thing to test.  There's an article on my blog how to do that.  Also make
sure you're not getting errors reading the ROM, which should be evident in
dmesg when you start the VM.  You'll eventually need to do something about
all the hyper-v stuff in your xml for an nvidia card, but it shouldn't hurt
until you install the nvidia driver and start seeing code 43 errors.  As
for not attaching the GPU until the end, I just find it easier to setup the
VM w/o it initially, for one, I don't need to be sitting in front of the
system to run through the installer and updates.
