Re: [Xen-users] xen, pvops & nvidia graphics
pciback was renamed to xen-pciback, I ran into this exact problem recently and bashed my head against the wall a bit to figure it out. Change your kernel cmdline to use xen-pciback.hide.
Good luck!

Hello all, this is my first post to the mailing list, so I hope this is the right way to ask a question.
I've installed xen on my laptop (Asus N51Vf, specs here: http://www.asus.com/product.aspx?P_ID=0Tc42s23bOdbbvY5), as I'm currently at university and don't have my proper desktop hardware to play with. The laptop supports IOMMU/Vt-d and has one PCI-e Geforce GT130M graphics card.
After some tweaking, it now boots up fine and I can start xend properly.
The problem is that I cannot detach my graphics card from Dom0 (I compiled the kernel with hot-(un)plug support, but I think the problem occurs somewhere else).
lspci outputs the following:

Remove a domain's pass-through pci device.
Also, passing the pciback.hide=(01:00.0)(00:02.0) argument to the pvOps kernel doesn't seem to have an effect (the appropriate modules are compiled statically into the kernel).
Can anybody help me with this?
Also, a little thing that's annoying me, but is not as critical, is that my Dom0 crashes when xserver starts if graphics drivers are enabled. I assume this is because even Dom0 is not in the correct address space for DMA, and according to http://wiki.xensource.com/xenwiki/VTdHowTo, there is no DMA translation for Dom0. I don't really need my graphics card for Dom0, but if anybody knows a way to get it working I'd appreciate it.
Thanks,
Kai
