/dev/vfio/vfio has 600 permissions, but in order for libvirt to be able to use it with default config, it needs to be 666. 3.10 already has a fix queued up, could it be backported to current F19? commit 664e9386bd05dbdfecfb28d6cf2fde983aabc65c Author: Alex Williamson <alex.williamson> Date: Tue Apr 30 15:42:28 2013 -0600 vfio: Set container device mode Minor 0 is the VFIO container device (/dev/vfio/vfio). On it's own the container does not provide a user with any privileged access. It only supports API version check and extension check ioctls. Only by attaching a VFIO group to the container does it gain any access. Set the mode of the container to allow access.

We can grab those, but is there a reason they aren't CC'd to stable? Particularly the second one?
Alex, see Comment #2, is there a reason these VFIO bits aren't heading for kernel stable tree?
I don't see that they meet the rules for stable. It's not a critical bug as far as the kernel is concerned. Note that both of these are going in during the 3.10 development phase, so there is no case of a released upstream kernel including one without the other.

I should have looked more first. I thought the rmmod fix was a stand-alone issue. I've grabbed both for F19.
