A while ago Jeremy responded the same question.
Per Jeremy:-  unmodified binary Nvidia driver would crash under Xen.
Modified driver should in the pvops kernel.

It's also my major concern as well.

Just wondering what it will take to get the nvidia binary driver
working on a pv_ops kernel.

It makes it difficult to debug without the source to the nvidia
driver, but I think it should be possible to get it to work without
changing the binary driver. If the dom0 kernel had access to all the
resources that a bare metal kernel did, then it should work right?

I'm using Jeremy's current master branch, and hypervisor 3.4.1-rc6 on
Ubuntu 9.04 64 bit.

Attached is my kern.log and Xorg.0.log when I attempt to start Xorg.
The screen goes blank and my monitor enters powersave mode, but I am
able to run an xterm and it appears to connect to the X server. Also
when the X server exits, it returns the console to a sane state.

I've also tried to get the nvidia driver to work with rebased suse
kernel and hypervisor 3.3 and 3.4. With that version kernel
it blacks the screen. I can remote ssh in to my pc, but I can't reboot
the pc. It needs a hard reset.
