lxc hypervisor does not support PCI devices

[Yerkanat Ramazanov]

OS: Ubuntu 14.04.02
OpenStack Kilo
Hypervisor: LXC

Nova: 1:2015.1.0-0ubuntu1~cloud0
libvirt-bin: Installed: 1.2.12-0ubuntu13~cloud0

I have lxc powered compute node with TeslaK40 card that I want to passthrough to VM. Tutorials that I used are:
https://wiki.openstack.org/wiki/Pci_passthrough
http://docs.openstack.org/kilo/config-reference/content/lxc.html

I can run simple VMs, however when I try to create VM with PCI then it fails.

Compute Node log:

I looked into /usr/lib/python2.7/dist-packages/nova/virt/libvirt/driver.py and found out that libvirt does not support pci passthrough for other hypervisors except (Xen,KVM,QEMU). Is it bug?

This node originally used KVM, however I could not passthrough PCI successully there, If anybody wants to look into (It would be huge help):

If any data is reqired I will provide it

This wishlist bug has been open more than a year without any activity.
I'm going to move it to "Opinion / Wishlist", which is an easily-obtainable queue of older requests that have come on.
This bug can be reopened (set back to "New") if someone decides to work on this.
