[qa] Test that l23network configurations persists after reboot

[Atsuko Ito]

As l23network configures system in runtime and then change the corresponding configuration files, it is necessary to validate that networking is working properly after reboot.

It could help us to find bugs that missed by unit tests like this one https://bugs.launchpad.net/fuel/+bug/1514421 in

actually we already have tests for networking config saving
https://github.com/openstack/fuel-qa/blob/master/fuelweb_test/tests/tests_strength/test_restart.py
They test our default network configuration(lnx bridges for nodes and ovs for neutron)

As you know we support ovs for everything as well and I am not sure whether we have tests for such kind of configuration

[Stanislav Makar (smakar)]

QA folks please verify and if we do not have- let's do it together

[Atsuko Ito (yottatsa)]

smakar, it seems that ceph_ha_one_controller_with_cinder_restart covers this case.

[Artem Panchenko (apanchenko-8)]

Guys,

We already have tests which verify network configuration on nodes after reboot:

https://github.com/openstack/fuel-qa/blob/4632e96a720b9d548e6650928b58d2904f083e04/fuelweb_test/tests/test_bonding.py#L302
https://github.com/openstack/fuel-qa/blob/4632e96a720b9d548e6650928b58d2904f083e04/fuelweb_test/tests/test_bonding.py#L386

And for example, here is a bug #1510072 which was found by these tests. As for OVS, it's impossible to enable Open vSwitch instead of native linux in Fuel, except using network templates. So I'm marking this bug as duplicate of bug #1517890
