We've seen instances where "Bad file descriptor" OSError was raised. This looks similar to 52d69be. Handle in the same way by ignoring the error and continuing execution. Signed-off-by: Sebastian Mitterle <smitterl@redhat.com>

Hi @smitterl thank you for opening this PR. Even though your change would fix the error message, I don't think we should do that, because IMO it hides the real issue. From your error trace sample, it looks like there might be some issue in |
This only happens some times in our environments. When it happens, from what I can tell, it's after the test fails and avocado(-vt?) is tearing everything down. You could try and run some of the tp-libvirt tests several times I'll send you a full test log via email. |

In tp_libvrt testing, We've seen many occurrences where "Bad file descriptor" OSError was raised during clean up phase when an external command is executed via `avocado.utils.process` utility. It happens when `SubProcess` class wants to flush the stdout and stderr of the external command after finishes. These kinds of errors might lead to stdout and stderr data loss, but during the tp_libvrt testing it leads to false positive failures, which makes test evaluation harder. This commit introduces a new config variable `omit_data_loss` which, when is enabled, will omit these errors, and they won't affect the overall test result.
