Description of problem: Using the upstream Aeolus 0.10.0 F16 rpms, Instances launched in VMware immediately fail with "Vanished" status when the instance name has spaces. For example, using an instance name of "InstanceA" works, but "Instance A" automatically fails. (every time) This is an excerpt from the /var/log/aeolus-conductor/dbomatic.log showing the problem: 2012-06-12 20:27:09 INFO Deltacloud refresh started 2012-06-12 20:27:09 INFO Deltacloud instances refresh started 2012-06-12 20:27:16 INFO updating instance state for InstanceF/F16-vmware: InstanceF-F16-vmware 2012-06-12 20:27:16 WARN caught deltacloud exception bad URI(is not URI?): http://localhost:3002/api/instances/Instance E-F16-vmware when updating instance Instance E/F16-vmware 2012-06-12 20:27:16 INFO known instance missing from provider: Instance E/F16-vmware Instance E-F16-vmware 2012-06-12 20:27:23 INFO updating instance state for InstanceD/F16-vmware: InstanceD-F16-vmware 2012-06-12 20:27:30 INFO updating instance state for InstanceC/F16-vmware: InstanceC-F16-vmware 2012-06-12 20:27:30 INFO Deltacloud instances refresh completed 2012-06-12 20:27:30 INFO Deltacloud refresh completed Version-Release number of selected component (if applicable): $ rpm -qa | grep -i aeolus | sort aeolus-all-0.10.1-1.fc16.noarch aeolus-conductor-0.10.1-1.fc16.noarch aeolus-conductor-daemons-0.10.1-1.fc16.noarch aeolus-conductor-devel-0.10.1-1.fc16.noarch aeolus-conductor-doc-0.10.1-1.fc16.noarch aeolus-configure-2.6.0-1.fc16.noarch rubygem-aeolus-cli-0.5.0-1.fc16.noarch rubygem-aeolus-image-0.5.0-1.fc16.noarch $ rpm -qa | grep -i deltacloud | sort deltacloud-core-0.5.0-2.fc16.noarch deltacloud-core-ec2-0.5.0-2.fc16.noarch deltacloud-core-rhevm-0.5.0-2.fc16.noarch deltacloud-core-vsphere-0.5.0-2.fc16.noarch rubygem-deltacloud-client-0.5.0-1.fc16.noarch How reproducible: Every time.
