[Users] Glance with oVirt

Dear ovirt users. I'm trying to setup an oVirt 3.3 installation using an already existing OpenStack glance service as an external provider. When I define the external provider, I put: Openstack Image as "Type" the glance service endpoint as "URL" (ie. http://xx.xx.xx.xx:9292) I used the openstack public url. check "Requires Authentication" put the administrator user/password/tenant in the following fields. Unfortunately the connection test always fails and the glance provider doesn't work in ovirt. In the engine.log I can see: 2013-09-24 15:57:30,665 INFO [org.ovirt.engine.core.bll.provider.TestProviderConnectivityCommand] (ajp--127.0.0.1-8702-3) Running command: TestProviderConnectivityCommand internal: false. Entities affected : ID: aaa00000-0000-0000-0000-123456789aaa Type: System 2013-09-24 15:57:30,671 ERROR [org.ovirt.engine.core.bll.provider.TestProviderConnectivityCommand] (ajp--127.0.0.1-8702-3) Command org.ovirt.engine.core.bll.provider.TestProviderConnectivityCommand throw Vdc Bll exception. With error message VdcBLLException: (Failed with VDSM error PROVIDER_FAILURE and code 5050) 2013-09-24 15:57:30,674 ERROR [org.ovirt.engine.core.bll.provider.TestProviderConnectivityCommand] (ajp--127.0.0.1-8702-3) Transaction rolled-back for command: org.ovirt.engine.core.bll.provider.TestProviderConnectivityCommand. The glance URL is reachable from the oVirt engine host, but looking with tcpdump on the glance service I noticed that no connections come up --- when I use "requires authentication" --- a connection happens if --- I do not use "requires authentication" --- (even if the test fails ultimately) My OS is CentOS-6.4 and my packages are the following: [root@rhvmgr03 ovirt-engine]# rpm -qa | grep ovi ovirt-host-deploy-1.1.1-1.el6.noarch ovirt-log-collector-3.3.0-1.el6.noarch ovirt-engine-cli-3.3.0.4-1.el6.noarch ovirt-engine-webadmin-portal-3.3.0-4.el6.noarch ovirt-engine-tools-3.3.0-4.el6.noarch ovirt-release-el6-8-1.noarch ovirt-engine-sdk-python-3.3.0.6-1.el6.noarch ovirt-iso-uploader-3.3.0-1.el6.noarch ovirt-host-deploy-java-1.1.1-1.el6.noarch ovirt-engine-userportal-3.3.0-4.el6.noarch ovirt-engine-backend-3.3.0-4.el6.noarch ovirt-engine-setup-3.3.0-4.el6.noarch ovirt-engine-3.3.0-4.el6.noarch ovirt-image-uploader-3.3.0-1.el6.noarch ovirt-engine-lib-3.3.0-4.el6.noarch ovirt-engine-restapi-3.3.0-4.el6.noarch ovirt-engine-dbscripts-3.3.0-4.el6.noarch Do you have some suggestion to debug or solve this issue? Thanks a lot. Best Regards R. Brunetti
