nova testsuite fails in the buildds.

[Chuck Short]

The ratelimiting test fails in the ubuntu buildds:

======================================================================
FAIL: test_second (nova.tests.api.openstack.test_ratelimiting.LimiterTest)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/build/buildd/nova-2011.1/nova/tests/api/openstack/test_ratelimiting.py", line 35, in test_second

Any reason why this would work on PPAs and not on main buildds ? Or is it just a random failure ?

I talked to Lamont last week and got him to look up the kernel config
on the buildds. Turns out they're running at HZ=100. That's too low
resolution for that particular test to function.

So... should we relax the test ? Skip it on buildds ?

This bug was fixed in the package nova - 2011.2~bzr925-0ubuntu1

---------------
nova (2011.2~bzr925-0ubuntu1) natty; urgency=low

  [Chuck Short]
  * New upstream release.

  [Soren Hansen]
  * Make the build fail if the test suite does. The test that used to
    fail on the buildd's has been complete rewritten. (LP: #712481)
  * Specify that we need Sphinx > 1.0 to build.
  * Remove refresh_bzr_branches target from debian/rules. It is not used
    anymore.
  * Clean up after doc builds on debian/rules clean.
  * Add a nova-ajax-console-proxy package.
  * Add Recommends: ajaxterm to nova-compute, so that nova-ajax-console-
    proxy will have something to connect to.
  * Stop depending on aoetools. iscsi is the default nowadays (and has
    been for a while).
  * Move dependency on open-iscsi from nova-volume to nova-compute.
    They're client tools, so that's where they belong.
  * Add a build-depends on python-suds.
  * Add logrote config for nova-ajax-console-proxy.
  * Add upstart job for nova-ajax-console-proxy.
