You can pass through pci devices to virtual machines using libvirt and
kvm, but... Does 400 gpu procesors = 400 pci-e cards? I'm not sure how
you would fit or provide power to all that in a single box, or where
you're going to get the few hundred thousand dollars it would cost. If
you're planning a project that will cost this much, I'd call up a few
hardware vendors and red hat for answers.

You might be interested in this whitepaper. It talks about running KVM
on a box with 48 cores and 512GB of RAM.
