When an instance terminates, the "allocated" field in the fixed_ips is
set to "0", but the "instance_id" field remains set. Once all the
addresses are in this state, new instances fail to start, and the
following error is logged by nova-network:
2012-06-22 23:09:34 ERROR nova.rpc.amqp
[req-1fea207d-cd65-4375-9a04-17ba1ab92e3e
22bb8e502d3944ad953e72fc77879c2f 76e2726cacca4be0bde6d8840f88c136]
Returning exception Zero fixed ips available. to caller
Which shows up in compute.log as:
2012-06-22 23:08:35 TRACE nova.rpc.amqp RemoteError: Remote error:
NoMoreFixedIps Zero fixed ips available.
Manually set instance_id=NULL in the fixed_ips table allows things to
work again.
We're running the 2012.1.1 release and we're using the FlatDHCP model.
Is this a known bug?
Thanks,
