Hello all,
I am a newbie to openvswitch and I have configured my openvswitch
configuration on top of ubuntu 12.04 as follows:
create ovs bridge:
ovs-vsctl add-br br0
Add physical nic as port on bridge:
ovs-vsctl add-port br0 eth0
Add vms on vlans with tags 100 and 200:
ovs-vsctl add-port br0 vnet0 tag=100 --- vm1
ovs-vsctl add-port br0 vnet1 tag=100 --- vm2
ovs-vsctl add-port br0 vnet2 tag=200 --- vm3
This configuration works perfectly i.e. the vms vm1 and vm2 are able to
ping each other but not vm3 until the networking is restarted.
There are two problems that I am facing now:
1) when the networking service is restarted, the vms configuration gets
erased from the ovs-vsctl. and "ovs-vsctl show" results into:
0e22c494-3f19-4236-b65f-6b3810dd0fc3
Bridge "br0"
Port "eth0"
Interface "eth0"
Port "br0"
Interface "br0"
type: internal
ovs_version: "1.4.0+build0"
How to make the vms configuration persistent?
2) On which port the trunks are configured? is it br0 or eth0? And say I
make one of them(br0 or eth0) a trunk port using
ovs-vsctl set port <eth0 or br0> trunks=100,200
Will I be able to ping vm1,vm2 from vm3 and vice versa? If not, then do I
need IP routing for this?
Regards,
- Nisha
