all vm have same image in network stats, and if they have more network card will have multiple stats

Seem to be a network flood.

Maybe do you have set "bridge-ageing 0" in your /etc/network/interfaces ?

in the start i think it's network flood too
but i have 100+ vm , and it all display same net in
maybe some bug?

Maybe try to do a tcpdump on the tapX interfaces, and look if you see same traffic everywhere, with wrong destination ip.

Do you see same traffic for netout too ? (because if it's a flood, you should only have same netin everywhere)


(Note: bridge-disable-mac-learning 1, need to restart of the vms to be applied)
