Monica, you may want to trace through the code using gdb. GDB backtrace
tells you where you came from and you can step forward through execution.
You can alway attach gdb to a running process. If using sandbox, you can
start vswitchd under gdb by using the '-g' option, as:
$ make sandbox
h different.

One possible solution is to create another bridge say brbond, and put eth0
and eth1 in it. You can then connect your bridge to 'brbond' using patch
ports. Patch ports will have their ofport numbers.

What solutions do you have in mind?
In this case, it seems there is a script involved in starting ovs. If
true, I wonder if it possible to create
the directory if necessary at the beginning of the script?

They are collected a few month apart and on different machines.
