This looks like a reasonable bug to file that would be trivial to fix. Nova should be a bit more forgiving if the http prefix is given. http://bugs.launchpad.net/nova -- Russell Bryant ------------------------------ Message: 5 Date: Thu, 10 May 2012 11:31:37 +0100 From: Pádraig Brady <P(a)draigBrady.com&gt; To: Fedora Cloud SIG <cloud(a)lists.fedoraproject.org&gt; Subject: Re: nova.rpc.amqp ValueError: too many values to unpack Message-ID: <4FAB9909.4070105(a)draigBrady.com&gt; Content-Type: text/plain; charset=UTF-8 On 05/09/2012 03:45 PM, Russell Bryant wrote: >> ----- Original Message ----- >> From: Pádraig Brady <P(a)draigBrady.com&gt; >> To: Ask Stack <askstack(a)yahoo.com&gt; >> Cc: Fedora Cloud SIG <cloud(a)lists.fedoraproject.org&gt; >> Sent: Wednesday, May 9, 2012 10:00 AM >> Subject: Re: nova.rpc.amqp ValueError: too many values to unpack >> >> On 05/09/2012 02:40 PM, Ask Stack wrote: >>> nova.conf on the second compute node: >>> >>> [DEFAULT] >> >>> glance_api_servers = http://172.20.0.51:9292 >> >> I think you need to remove the http:// prefix from the above > > On 05/09/2012 10:16 AM, Ask Stack wrote: >> Pádraig. >> Thanks! that worked. > > This looks like a reasonable bug to file that would be trivial to fix. > Nova should be a bit more forgiving if the http prefix is given. > > http://bugs.launchpad.net/nova I'm not sure. The error message isn't too bad. Also it's generally best to limit input combinations. What about 'https', trailing '/' etc. Also maybe in future http might not be used, which would involve config editing to support. cheers, Pádraig. ------------------------------ _______________________________________________ cloud mailing list cloud(a)lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/cloud End of cloud Digest, Vol 29, Issue 6 ************************************
