Hi, I could only check the setup now but thanks for the tips, <div>it worked! So the trick was to have the rabbit sevice on the compute host</div><div>as well. Also there have been several other emails in the threat with</div>
<div>more detailed info (e.g. Multinode=true instead of multinode=1, etc).</div><div><br></div><div>Thanks for the help!</div><div><br></div><div>/Nico.</div><div><br><div class="gmail_quote">On 23 May 2012 20:55, Dan Wendlandt <span dir="ltr"><<a href="mailto:dan@nicira.com" target="_blank">dan@nicira.com</a>></span> wrote:<br>

<div><font face="arial, helvetica, sans-serif" style><br></font></div><div><font face="arial, helvetica, sans-serif" style>There seems to be a bug in multi-node devstack that if you do not specify "rabbit" as one of the enabled services on each compute node, the nova-compute on the compute node tries to contact the rabbit server on localhost, rather than on the IP specified by <span style="line-height:18px;white-space:pre-wrap">RABBIT_HOST. </span></font></div>

Looking at the nova-compute log on your compute hosts could probably help determine if this is the issue, as there would be errors due to the failure to connect to rabbit. Putting "rabbit" in the set of ENABLED_SERVICES on all nodes seems to have worked for me as a work around.</span></font></div>
