Hi, all


I want to run nova on my raspberry pi 2 model B. It has a Cortex-A7<https://en.wikipedia.org/wiki/ARM_Cortex-A7> CPU, and its architectur is ARM v7. So, maybe there is something different when run nova on it.


I have qemu 2.1.2, libvirt 1.2.9, python 2.7.9, and nova stable/liberty.

I can setup nova. But after that, when I run either nova service, such as nova-all, nova-api, nova-manage db sync, I got this error.


------------------------------------------

/home/pi# nova-manage db sync

Traceback (most recent call last):

    (self.namespace, name))

stevedore.exception.NoMatches: No 'nova.ipv6_backend' driver found, looking for 'rfc2462'
-------------------------------------------------


I can't find any useful info on the internet about ipv6_backend, so I have to come here for help.


And I don't think this error has any matter with nova.conf or api-paste.ini, because even I changed them, the error was the same.


If it's necessary, i'll paste any info later.


Thank you
