<p>Hello Pavel</p>
<p>What you mean by another oVirt instance ? In one Datacenter it
has 2 different clusters (or Datacenter in oVirt way of
orrganizing things), but in the other Datacenter the oVirt Node is
standlone.</p>
<p>Let me know.</p>

<p class="MsoNormal"><span style="font-family:Arial">Hello.<br>
<br>
I am facing a pretty bizzare problem in two of my Nodes
running oVirt. A given VM running a few hundred Mbps of
traffic simply stops passing traffic and only recovers after
a reboot. Checking the bridge with 'brctl showmacs BRIDGE' I
see the VM's MAC address missing during this event.<br>
<br>
It seems the bridge simply unlearn the VM's mac address
which only returns when the VM is rebooted.<br>
This problems happened in two different Nodes running in
different hardware, in different datacenter, in different
network architecture, different switch vendors and different
bonding modes.<br>
<br>
The main differences these Nodes have compared to others I
have and which don't show this problem are:<br>
- The CentOS 7 installed is a Minimal installation
instead of oVirt-NG<br>
- The Kernel used is 4.12 (elrepo) instead of the
default 3.10<br>
- The ovirtmgmt network is used also for the Virtual
Machine showing this problem.<br>
<br>
Has anyone have any idea if it may have anything to do with
oVirt (any filters) or any of the components different from
a oVirt-NG installation ?<br>
<br>
Thanks<br>
Fernando<br>
