[Openstack] Instance cannot access internet

What do you mean by external interface? I access and get internet through eth0 on my host.
So does that mean I will use eth0?

Just want to be sure cause some documents say I should add my private interface(eth1) to br-ex

Thank you!

hello jake,

Can't see that you have added any external interface to br-ex in ovs-vsctl show command output.


ovs-vsctl add-br br-ex
ovs-vsctl add-port br-ex <external interface>
ip link set up br-ex
