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 ? Fernando On 23/07/2017 07:51, Edward Haas wrote:
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, Edy,

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 only with a VM reboot.
When I last saw the problem I run brctl showmacs ovirtmgmt and it shows me the VM's mac adress with agening timer 200.19. After the VM reboot I see the same mac with agening timer 0.00. I don't see it in another environment where the ovirtmgmt is not used for VMs.
Does anyone have any clue about this type of behavior ?
