Ok, let's say I have three namespaces. I want to use ovs. How can I do that?
Thanks,
Daniele

Hello,
I'm trying to connect two network namespaces (ip netns) with a two
port openvswitch, on the same physical machine. I've had no success.
Up to now I tried with this command sequence:
===
ip netns add test_ns1
ip netns add test_ns2
ip tuntap add dev tap1 mode tap
ip tuntap add dev tap2 mode tap
ovs-vsctl add-br test_br
ovs-vsctl add-port test_br tap1
ovs-vsctl add-port test_br tap2
ip link set tap1 netns test_ns1
ip link set tap2 netns test_ns2
$EXEC_NS1 ifconfig tap1 192.168.1.101 up
$EXEC_NS2 ifconfig tap2 192.168.1.102 up
$EXEC_NS1 ping -c 2 192.168.1.102
===
The ping at the end reports "Destination Host Unreachable".
I tried also with the following variations, with no success either:
1. wrote a program that creates the tap interfaces and keeps them
open instead of using "ip tuntap". No data is read on either tap1
or tap2 on the file descriptor.
2. create tap1,2 inside the namespaces and connect them from there
instead of creating in the default ns and then moving them.
The ovs log is full of errors since, after moving the interfaces
inside the namespace, it is unable to find them. Apparently this
is normal and accepted behaviour, according to google.
What am I doing wrong?
How can I query some status out of ovs? Stuff like port status,
counters, etc?
Thanks,
Daniele
