   cc @shwstppr pl check that the base branch changed to 4.17 causes some extra changes/commits (rebase/merge 4.17 branch on your PR branch). I think since you're adding tests, the 4.17 branch can benefit from this which has the ipv6 feature.

Review Comment:
   if the parent throws an exception, the next part of the cleanup will not be executed. Is that intentional?
   or should it be like,
   ```suggestion
           try:
               super(TestIpv6Network, cls).tearDownClass()
           finally:
               if cls.test_ipv6_guestprefix != None:
                   cmd = deleteGuestNetworkIpv6Prefix.deleteGuestNetworkIpv6PrefixCmd()
                   cmd.id = cls.test_ipv6_guestprefix.id
                   cls.apiclient.deleteGuestNetworkIpv6Prefix(cmd)
   ```

Review Comment:
   in this case it might be
   ```suggestion
           try:
               if self.thread and self.thread.is_alive():
                   self.thread.join(5*60)
               #Clean up, terminate the created templates
           except Exception as e:
               raise Exception("Warning: Exception during cleanup : %s" % e)
           finally:
               super(TestIpv6Network, self).tearDown()
           return
   ```
   this structural part of this sugestion *is* a question, but it seems that any resources created during the test would not get cleaned if the `thread.join` leads to an exception.
   the call to super is really very convenient, and if you use vms very much needed.

   ```suggestion
               self.cleanup.append(ipv6_publiciprange)
               self.debug("Created IPv6 public range with ID: %s. Deleting it before failure" % ipv6_publiciprange.id)
   ```
   a bit pompeus, but on io errors we still want to clean up as much as possible.

Review Comment:
   this appending to the cleanup list should really be inside the `createVpcOfferingInternal()`, directly after the create.
   in this way an exception in the `update()` would leave garbage.

           finally:

   ```
   , unless of course we are sure no exceptions can be thrown in the `Configurations.update(..)`, but I think it involves network, so pretty sure it can.

   @blueorangutan test
   
   @rohityadavcloud @weizhouapache @DaanHoogland added smoke tests may add ~1.25hrs to smoke test run. Does it make sense to move some of the test cases to a test file in component  dir?

   > I think it makes sense to only leave miniml tests in the smoke dir, @shwstppr . The rest we´d only want to run on subject specific PRs and releases. €0.02
   
   agree with @DaanHoogland 
   we should run the component tests at least once a month (we need to fix all component tests before run, or move failed component tests to a separated folder)
