Description of problem:

Note:
------------
This is a summary provided from mmartinv/Olimp/Alejandro discussion from: https://bugzilla.redhat.com/show_bug.cgi?id=1838559

Test Scenario
===========================

Engine versions tested:
----------------------------------
oVirt Engine: Software Version:4.3.9.4-1.el7
RHVM: Software Version:4.3.7.2-0.1.el7
RHVM: Software Version:4.3.9.4-1.el7


How I have created the nics?
--------------------------------
- Engine Administrator portal -> Network -> Networks -> New
             Name: nic${number}

  * I have repeated that for 15 times. 

- Engine Administrator portal -> Network -> Networks
        * On NIC 10 -> Edit -> Set nameserver to 8.8.8.8  (or multiple nameservers if you prefer)


Run the tool:
-----------------------
$ go get github.com/ovirt/go-ovirt
$ go run reproducer.go (bellow the code)

2020/05/29 08:59:05 nic10            <---------- only two
    

Workaround
-----------------------------------
$ vi ~/go/src/github.com/ovirt/go-ovirt/readers.go
