<p><span>Hi, all</span></p>
<p><span><br>
</span></p>
<p><span>I want to run nova on my raspberry pi 2 model B. It has a <a href="https://en.wikipedia.org/wiki/ARM_Cortex-A7" title="ARM Cortex-A7" style="text-decoration: none; color: rgb(11, 0, 128); font-family: sans-serif; font-size: 14px; line-height: 22.4px; background-image: none; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;">Cortex-A7</a> CPU,
and its architectur is ARM v7. So, maybe there is something different when run nova on it.<span style="font-family: sans-serif; font-size: 14px; font-weight: bold; line-height: 22.4px; text-align: center;"></span></span></p>
<p><span><br>
</span></p>
<p><span>I have qemu 2.1.2, libvirt 1.2.9, python 2.7.9, and nova stable/liberty.</span></p>
<p><span>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.</span></p>

<p></p>
<p><span><br>
</span></p>
<p><span>I can't find any useful info on the internet about ipv6_backend, so I have to come here for help.</span></p>
<p><span><br>
</span></p>
<p><span>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.</span></p>
<p><span><br>
</span></p>
<p><span>If it's necessary, i'll paste any info later.</span></p>
<p><span><br>
</span></p>
<p>Thank you</p>
