You are loading the config file while flowvisor is running. Unfortunately, the internal database does not like this. Luckily, you do not need to do this. Once you have run sudo /etc/init.d/flowvisor start, flowvisor is running and ready for use. If you want to load a specific config file then run fvconfig load config.json when fv is _not_ running, but this is usually unnecessary for a fresh fv install.
The error message is relatively cryptic, could you submit a bug report on the issue tracker? -- Ali Al-Shabibi (sent from handheld) On 11 déc. 2012, at 06:53, Humphrey Lee <iramani...@gmail.com> wrote: > Ali, > > I thought so.
