Hello.
Despite I didn't get any feedback on this topic anymore I just wanted to
let people know that since I moved the VM to another oVirt Cluster
running oVirt-Node-NG and Kernel 3.10 the problem stopped happening.
Although I still don't know the cause of it I suspect it may have to do
with
Hello Fernando,
Have you taken the tcpdump in the VM to see what traffic is sent out?
Your host is a Centos 7.3? If so how come it has such a kernel version?
Have you see anything in /var/log/messages when it gets disconnected?
Thanks,
Edy.

Hello Edwardh and all.
I keep getting these disconnects, were you able to find anything about
to suggest changing ?
As I mentioned this machine different from the others where it never
happened uses the ovirtmgmt network as VM network and has kernel 4.12
instead of the default 3.10 from Cent

Hello Edward, this happened again today and I was able to check more
details.
So:
- The VM stopped passing any network traffic.
- Checking 'brctl showmacs ovirtmgmt' it showed the VM's mac address
missing.
- I then went to oVirt Engine, under VM's 'Network Interfaces' tab,
clicked Edit and ch
Not tried this yet Edwardh, but will do at next time it happens. THe
source mac address should be the mac as the VM. I don't see any reason
for it to change from within the VM ou outside.
What type of things would make the bridge stop learning a given VM mac
address ?

Have you tried to use tcpdump at the VM vNIC to examine if there is traffic
trying to get out from there? And with what source mac address?
Thanks,

Has anyone had problem when using the ovirtmgmt bridge to connect VMs ?
I am still facing a bizarre problem where some VMs connected to this
bridge stop passing traffic. Checking the problem further I see its mac
address stops being learned by the bridge and the problem is resolved
