Hi,

I'm currently working on bringing up a devstack install using the master
branch. Basic install went OK but now I am trying to configure TSN and TOR
agents for use with hardware VTEPs. I've copied the vrouter-agent config
and tor-agent config from a working 2.1 install however I am having issues
starting the tsn process:


houtz@contrail:~$ /usr/bin/contrail-vrouter-agent
--config_file=/etc/contrail/contrail-vrouter-agent.conf
log4cplus:ERROR No appenders could be found for logger (SANDESH).
log4cplus:ERROR Please initialize the log4cplus system properly.
Config file </etc/contrail/contrail-vrouter-agent.conf> parsing completed.
contrail-vrouter-agent:
controller/src/vnsw/agent/contrail/linux/pkt0_interface.cc:52: virtual void
Pkt0Interface::InitControlInterface(): Assertion `0' failed.
Aborted (core dumped)

log reports:

I currently have a pkt0 interface that contrail created though the fact
that I can't even delete it is probably related:

dhoutz@contrail:~/.ssh/contrail-installer$ ifconfig pkt0

dhoutz@contrail:~/.ssh/contrail-installer$ tunctl -d pkt0
TUNSETIFF: Device or resource busy


Anyone have any pointers on getting tsn up and running?

Thanks!
Dan
