What's more, the steps I followed is from the openvswitch FAQ document in http://docs.openvswitch.org/en/latest/faq/issues/
But even follow these steps, every time I need to reconfigure the bridge interface such as br0's ip address etc ... Common Configuration Issues - Open vSwitch Documentation<http://docs.openvswitch.org/en/latest/faq/issues/> A: More than likely, you’ve looped your network. Probably, eth0 and eth1 are connected to the same physical Ethernet switch. This yields a scenario where OVS receives a broadcast packet on eth0 and sends it out on eth1, then the physical switch connected to eth1 sends the packet back on eth0, and so on forever. docs.openvswitch.org Q: I can’t unload the openvswitch kernel module. Why? A: The userspace might still hold the reference count. So rmmod openvswitch does not work, for example: $ lsmod | grep openvswitch openvswitch 155648 4 nf_conncount 24576 1 openvswitch Use the command below to drop the refcnt: $ ovs-dpctl del-dp system@ovs-system $ rmmod openvswitch 发送自 Outlook<http://aka.ms/weboutlook> ________________________________ 发件人: [email protected] <[email protected]> 代表 pei Jikui <[email protected]> 发送时间: 2019年3月20日 15:02 收件人: [email protected] 主题: [ovs-discuss] replace the openvswitch.ko without losing the bridge interface's configuration When I replace the openvswitch.ko with a new modified one, the configuration on the bridge such as br0 is lost. I need to reconfigure its ip address and bring it up again manually. Is there any alternative that we could replace the openvswitch.ko without losing the bridge interfaces’ configuration? The steps I used to replace the openvswitch on the centos. 1) Compile the openvswitch make -j `nproc` make install 2) Replace the openvswitch.ko ovs-dpctl del-dp system@ovs-system rmmod openvswitch insmod ./datapath/linux/openvswitch.ko ovs-ctl restart Thanks.
