Hi,
We are facing an issue with Openvswitch 2.0.0 package built from source
code for Ubuntu 13.04.
We have patched the openvswitch init script to invoke another script, that
creates two OVS bridges during openvswitch start.
The problem is that out of some 1000 runs, the following issue is hit in
around 5 runs.
The bridges are getting created in the OVSDB. But the physical bridge is
not created.
root@compute-node2:~# ovs-ofctl show br-int
ovs-ofctl: br-int is not a bridge or a socket
root@compute-node2:~# ovs-ofctl show br-tun
ovs-ofctl: br-tun is not a bridge or a socket
=======================================
root@compute-node2:~# lsmod | grep openvswitch
openvswitch 81375 0
gre 12989 1 openvswitch
libcrc32c 12615 1 openvswitch
=====================================
root@compute-node2:~# ovs-vsctl --db tcp:127.0.0.1:6622 show

ovs_version: "2.0.0"
Is this a known issue in openvswitch ? Could this be caused because
sometimes this bridge creation gets invoked before the kernel module is
properly loaded and initialised ?
Any inputs is appreciated.
