[ovs-dev] Network namespace support for OpenVSwitch

[Sapan Bhatia]

Hi everyone,

I have been working on trying to get Openvswitch running on PlanetLab
(www.planet-lab.org.) The idea is to enable experimenters to use
openvswitch with virtual devices. On PlanetLab, user processes run in
their own network (netns) namespaces. My thought at first was that as
long as one user's devices are isolated from other users, the switch
configuration should be isolated as well (though I needed to change
init_net to look up the namespace of the associated container in
datapath.c.)

However, it appears that vswitchd is configured via a single
configuration file. Is it possible to run multiple instances of
vswitchd, or plans to this effect? Any guidance or starting pointers
will be much appreciated.

Thank you,
Sapan
