<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>
