Hi All, I encountered a problem configuring the cloud controller of Openstack Nova (Diablo release) on Ubuntu 11.10 x64 server. I've already done 'source novarc', the commands 'euca-describe-availability-zones verbose' and 'euca-describe-instances' works just fine, but 'euca-describe-images' cannot be carried out, with the following returning message: UnknownError: An unknown error has occurred. Please try your request again. Thus I cannot publish img on this server using 'cloud-publish-tarball'. All the configuration is identical to the official starter guide, BTW: http://docs.openstack.org/diablo/openstack-compute/starter/content/Nova_conf-d2s367.html Reboot doesn't help; I've even tried re-installed Ubuntu and all Nova components all over again and this problem is still there. Do someone know something about it? Any help is appreciated :) Thanks. Regards, Chang -------------- next part -------------- An HTML attachment was scrubbed...
