We can't turn off the seed unless we change the network topology; we need to make sure if we do that that we don't invalidate the test structure. > Small potatoes I know, but it wouldn't be complicated to do any of these > and it would also help test real scenarios we want to test (seed going > away, undercloud node going away). > > _______________________________________________ > OpenStack-dev mailing list > OpenStack-dev@lists.openstack.org > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev I like this. I also like much of the spread of ideas that came up - lets capture them to an etherpad and link that from a blueprint for future selves finding it. In particular I'd like to make being able to use OpenStack a J series goal, though it doesn't help with local dev overheads. -Rob -- Robert Collins <rbtcoll...@hp.com> Distinguished Technologist HP Converged Cloud _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
