<title>Problem</title>
<para>When you attach a nova volume to a VM, you will see the
error with stack trace in

The JSON serializable issue is caused by an RPC response
timeout.</para>

<para>Make sure your iptables allow port 3260 communication on
the ISC controller. Run this command:</para>
<screen><prompt>#</prompt> <userinput>iptables -I INPUT &lt;Last Rule No> -p tcp --dport 3260 -j ACCEPT</userinput></screen>
<para>If the port communication is properly configured, you
can try running this command.</para>
<screen><prompt>#</prompt> <userinput>service iptables stop</userinput></screen>

<para>This service does not exist on Debian or
Ubuntu.</para>
