Installing openstack in venv doesn't work

[Dmitry Guryanov]

Devstack can install all python packages in python's virtual environments, if you set USE_VENV to True in local.conf. But there is a bug and nova-api service can't run nova-rootwrap, so it fails to start.

Fix proposed to branch: master

I just run stack.sh with adding USE_VENV=True on local.conf
It is succeeded.
Is any other condition to reproduce this problem?

my local.conf is same as samples/local.conf.

I run in on centos 7, maybe sudo on Ubuntu is more permissive.

    Fix path setup in add_sudo_secure_path

    There are two bugs in add_sudo_secure_path.

    Firstly we don't properly check if the file exists, so always append
    the new line. This will overwrite any existing changes.

    Secondly the logic for checking if the path exists is inverted, so we
    miss adding paths when we should. This particularly causes failures
    when installing with virtualenv's since the paths are inside the
    virtualenv, rather than the standard system locations.
