DVR functional test fails on devstack

[Inessa Vasilevskaya]

Steps to reproduce:
1. Ubuntu server 15.04 VM (with python-virtualenv), freshly cloned neutron and devstack

2. Create env, install tox and configure for functional testing
python tools/install_venv.py
source .venv/bin/activate
pip install tox
sudo ./tools/configure_for_func_testing.sh ../devstack -i
tox -e dsvm-functional

3. 4 tests in test_dvr_router module will fail:
neutron.tests.functional.agent.l3.test_dvr_router.TestDvrRouter.test_dvr_ha_router_failover
neutron.tests.functional.agent.l3.test_dvr_router.TestDvrRouter.test_dvr_router_lifecycle_ha_with_snat_with_fips
neutron.tests.functional.agent.l3.test_dvr_router.TestDvrRouter.test_dvr_router_lifecycle_ha_with_snat_with_fips_nmtu
neutron.tests.functional.agent.l3.test_dvr_router.TestDvrRouter.test_dvr_router_lifecycle_without_ha_with_snat_with_fips

Tox run result - http://paste.openstack.org/show/490477/

After step-by-step debugging test_dvr_ha_router_failover I discovered that the root to the problem with 2 out of 4 tests was the absence of pid_files in router's external/pids directory. More logs here - http://paste.openstack.org/show/490684/.

I cannot see the failure in my env(Ubuntu 14.04 & Neutron trunk version).

> freshly cloned neutron
Is that trunk?

[Inessa Vasilevskaya (ivasilevskaya)]

Sorry for not specifying version - I meant both neutron and devstack master branches.

I checked on ubuntu 14.04 - same test failures for me.

[Hirofumi Ichihara (ichihara-hirofumi)]

I cannot reproduce. Can you show that the error happens in gate job logs or anything else?
