Public bug reported:

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
