We created a ovs bridge br0 in a VM launched by openstack, and add eth0 as its port, assign the IP address to br0 port instead of eth0. But the br0 is not reachable from external, before bridge is created, eth0 is working well in the VM.
The reason is that br0 doesn't get the same mac address as eth0. eth0 mac address in openstack VM starts with "fa" which U/L bit is set, but openvswitch doesn't select any Local address for bridge port, it causes ovs bridge doesn't work in the VM. One question is that why openvswitch limits Local address to be used? Secnond, Is there any solution to use ovs bridge in the VM if I don't want manually change br0's mac address?
