Hi, I am trying to associate an floating IP to an instance from API in my Essex environment, and get the error "404 Not Found". I found someone have filed an invalid bug (the link is https://bugs.launchpad.net/nova/+bug/917064), I followed the information and tried several request formats as below, but all are failed. 1. curl -k -D - -H "X-Auth-Token: 7f48c07af3b842d1b9c0f15a37ddd956" -X 'POST' -d @test.json -v http://localhost:8774/v1.1/53869b3cd0cc40a28a826422a37622da/os-floating-ips/1/associate-H 'Content-type: application/json' The file test.json: *{* * "associate_address" : {* * "fixed_ip" : "192.168.20.3"* * }* *}* * * 2. curl -k -D - -H "X-Auth-Token: 7f48c07af3b842d1b9c0f15a37ddd956" -X 'POST' -d @test.json -v http://localhost:8774/v1.1/53869b3cd0cc40a28a826422a37622da/os-floating-ips/1/action -H 'Content-type: application/json' The file test.json: *{* * "addFloatingIp": {* * "address" : "10.100.20.17"* * },* * "associate_address" : {* * "fixed_ip" : "192.168.20.3"* * }* *}* 3. curl -k -D - -H "X-Auth-Token: 7f48c07af3b842d1b9c0f15a37ddd956" -X 'POST' -d @test.json -v http://localhost:8774/v1.1/53869b3cd0cc40a28a826422a37622da/os-floating-ips/1/addFloatingIp -H 'Content-type: application/json' The file test.json: *{* * "associate_address" : {* * "fixed_ip" : "192.168.20.3"* * }* *}* I am wondering what is the correct request format or just a bug? It will be much appreciated if someone can give me some hints. Thanks, Sam -------------- next part -------------- An HTML attachment was scrubbed...
