Network suite has indeed been failing randomly recently. More often than not it was due to timeouts while waiting for connections to the hosts, timeouts while waiting for hosts to reach deserted statuses, and in the above I also see what looks like a sock error on port 22. Not only are the failing tests random but also usually the next nightly passes. This leads me to believe that the cause of the failures is outside the scope of the tests code.

On the next build - different errors:

https://jenkins.ovirt.org/blue/organizations/jenkins/ovirt-system-tests_standard-check-patch/detail/ovirt-system-tests_standard-check-patch/13581/pipeline

- basic_suite_4.3.el7.x86_64 - failed
- basic_suite_master.el7.x86_64 - failed
- network_suite_4.3.el7.x86_64 - failed
- network_suite_master.el7.x86_64 - failed

With the current state OST CI is not useful to anyone. Builds take hours
and fail randomly. This wastes our limited resources for other projects
and makes contribution to this project very hard.
