Title:
Cannot load 'instance' in the base class - problem in floating-ip-list
Status in OpenStack Compute (Nova):
Fix Released
Bug description:
I tried the following on VMware using the VMwareVCDriver with nova-
network:
1. Create an instance
2. Create a floating IP: $ nova floating-ip-create
3. Associate a floating IP with the instance: $ nova floating-ip-
associate test1 10.131.254.249
4. Attempt a list of the floating IPs:
$ nova floating-ip-list
ERROR (ClientException): The server has either erred or is incapable of
performing the requested operation. (HTTP 500) (Request-ID:
req-dcb17077-c670-4e2a-8a34-715a8afc5f33)
It failed and printed out the following messages in n-api logs:
