No module named privsep.libvirt for stable/pike

[Memo Garcia]

Description
===========
I'm trying to run nova-compute from stable/pike on archlinux using python 2.7.14 (python 3 I had the same luck) and I keep getting this error when I run it.

Steps to reproduce
==================

git clone -b stable/pike --depth=1 https://github.com/openstack/nova.git /opt/nova
python2 -m pip install -e . && tox -e genconfig
nova.conf configuration and nova-compute.conf configuration
nova-compute

Expected result
===============

nova-compute to start working

Actual result
=============

I tried the command you gave (only the clone) but I can't find the lines you mentioned... maybe wrong method usage?
