Go runs tests in parallel for different packages in parallel. The service update test was disabling and re-enabling all compute services, and if this ran at the same time as another test that created a server then the server creation (and therefore the test) would fail. There does not appear to be any way to resolve this. We could run all integration tests serially instead, but this would be a backwards steps that will massively increase test run time. We could also rewrite the test to only disable 1 of N nova-compute services, but that would require us to fence off this compute node in all other tests using non-default parameters to server create. Given the lack of better options, we simply remove the test and assume our testing to date on this method has been good enough and unit tests will be enough to carry us forward.

I wanted to test the new "hold" label, but Github is excruciatingly slow at running jobs today... |
|
Got another example of this here #3120 |
|
@stephenfin Do we need a backport here= |
|
As I stated in #3120, I'm not sure the root of the problem is parallelization. Why does it only fail on master? To me this looks caused by a change in openstack, for example where service update was previously blocking and it's no longer the case. |

According to our CI history, it started failing between May 22th and May 25th. |
Nothing stands out for me from the two weeks prior to this. |
