Hi, I just installed RDO all-in one( KILO release) on a Centos 7 . Installation is OK. Image creation also. But when trying to launch an cirrus ( or fedora22) instance I got following error : Error: The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-2c739a95-5974-423f-b01c-da832f3a027d) FYI, nova-api.log shows this error : 2016-04-21 10:16:40.176 4080 INFO nova.api.openstack [req-2c739a95-5974-423f-b01c-da832f3a027d e41c083d61d44b30ab24e13a889d8093 233c7454196b467580d8d68a6113ba6b - - -] http://..... /v2/233c7454196b467580d8d68a6113ba6b/servers returned with HTTP 500<http://.....%20/v2/233c7454196b467580d8d68a6113ba6b/servers%20returned%20with%20HTTP%20500> Nova service list : nova-manage service list nova-consoleauth internal enabled :-) 2016-04-21 14:42:49 nova-scheduler internal enabled :-) 2016-04-21 14:42:47 nova-conductor internal enabled :-) 2016-04-21 14:42:48 nova-compute nova enabled :-) 2016-04-21 14:42:48 nova-cert internal enabled :-) 2016-04-21 14:42:48 Any idea what it could be ?
