What are you actually trying to achieve as your end result ?

PCI device assignment doesn't entirely make sense in the LXC world. Since
the container shares a kernel with the "host" OS, there's nothing to
really assign the PCI device to.

If you're trying to use a PCI NIC, then is the bridging/NAT setup not
sufficient ?

If you're trying to use a block device, I've got a patch which will
let libvirt's LXC code automatically mount any host block as a filesystem
inside the container at startup. Your next mail about cgroups device ACL
makes me think this is what you're trying todo...

If neither of these are suitable, then we could think about how to support
logical device assignment. ie assign a NIC, or assign a block device,
rather than assigning the PCI device proividing it.

Daniel
