I've personally never even heard of packstack, so I can't comment on how to fix/where to file a bug etc...<br>
<br>
Maybe someone else can?<br>
<br>
Thanks,<br>

As the nova user, manually attempt that SSH command.. Then figure out<br>
why it can't SSH to the other node. It should work (or at least get<br>
further) once you do.<br>
