Comment 2 for bug 2011824

In the last job which passed, this test was skipped:

[1] https://logserver.rdoproject.org/openstack-periodic-integration-main/opendev.org/openstack/tripleo-ci/master/periodic-tripleo-ci-centos-9-ovb-1ctlr_2comp-featureset020-master/d59ec78/logs/undercloud/var/log/tempest/tempest_run.log.txt.gz

~~~
{3} tempest.scenario.test_network_advanced_server_ops.TestNetworkAdvancedServerOps.test_server_connectivity_live_migration ... SKIPPED: Live migration is not available.
~~~

In the last run for some reason this test was not skipped by tempest itself and failed because we don't have shared storage.
