Hello all,
I had been trying to set up cimtest to work on my machine for a couple of days without success. So yesterday I started to dig the code and found that every command is sent via ssh, even if the test is supposed to run locally.
The reason of cimtest not working was exactly that did not have the ssh keys set up properly. By fixing that configuration, I was able to make the test work as expected. :)
But I was still intrigued with the fact that every command is sent via ssh, thus taking cimtest a very very long time to complete. So I hacked a simple patch to try to workaround this issue:
[snip]
As you can see, it is a quick check if 'ip' is neither localhost nor 127.0.0.1, which only in that case the command is sent via ssh.
Note that this patch triggers some other issues, which I hope to be able to fix soon. But there is already a *huge increase* in the performance. I have used the most simpler and probably not the most correct measure:
So I have went somewhat deeper in my investigations and found most of the issues triggered by that patch. An updated version can be found attached to this message.
_BUT_, I can't really tell if it is actually intended that everything runs with ssh. Taking a look on the test results, it is noticeable that cimtest behaves in a different way, as follows.
Now the behavior of cimtest with the patch applied is much more similar to the version without the patch. 158 tests are labeled PASS, and only 3 that were FAIL without patch are now SKIP. Unfortunately I don't have access to the test machine at the moment, so I am not able to provide the detailed report, which I will do as soon as possible.
I would really appreciate comments from the experts on this issue. IMHO, it is something really worthy and if there are any tests that are required to run remotely, I could work on a proper fix to try to achieve the same results.
Still waiting for some light regarding this issue. Best Regards, -- Eduardo de Barros Lima Software Engineer, Open Virtualization Linux Technology Center - IBM/Brazil eblima@br.ibm.com
