[Xen-users] Dedicated Nvidia PCI passthrough for Linux PVM

[Brian Krusic <brian@xxxxxxxxxx>]

Hi,

Not trying to be obnoxious on this list.

I thought perhaps phrasing the subject line specific will catch some ones eye (hopefully).

Would like some help on 2 issues.

1 -  I have PCI pass through working for an Nvidia card which is my 2nd graphics adapter and I wish to dedicate it to a particular domU.

I had to mod my initrd as follows;

mkinitrd -f --preload=pciback /boot/initrd-$(uname -r).img $(uname -r)

And also include the following line in /etc/modprob.conf (boot line in grub.conf doesn't work for me);

options pciback hide=(07:00.0)

Besides adding the below line in my domU config file;

pci = ['07:00.0']

Do I need to add anything else to the domU config?

What else do I need to do before compiling Nvidia drivers (I found a few write ups that tell you how to do this) in that domU?

2 - The line of pci = ['07:00.0'] works for traditional domU configs but what would be the syntax for a the new style config used in 3.4.x?

Thanks in advance,

- Brian
