Hello Ben:
Thanks for your replying. I look the following information, and I find some solutions: brcompat_mod: exports duplicate symbol br_should_route_hook (owned by bridge) I think the problem is brcompat module not loaded due to bridge module prevent it. And I edit /etc/modprobe.d/blacklist to Add: blacklist bridge But when I delete the bridge-utils package ( apt-get purge bridge-utils ), it also delete libvirt and kvm relative packages... So I take measure to remove bridge module by using rmmod command and restart the OVS, and it works. Thanks again for your helping.
