Deletion of auto-assigned floating IPs fails, but is required to delete a VM

[bhagemeier]

Due to interoperability issues with other OCCI implementations, we have enable automatic assignment of floating IPs to our instances. This leads to the following problem:

1. create VM
2. delete VM fails because of the auto-assigned floating IP

This is what the client receives in the response body:

1. create VM
2. delete auto-assigned floating IP link

3. delete VM SUCCESSFUL

So, despite the deletion of the networklink being reported as failed, something changed, such that the VM can be deleted afterwards.

Is this still the behavior openstack shows? If so we can setup some if-else clauses to deal with it I guess

Hi Thijs,

we have deactivated auto-assigned floating IPs as our client can now
assign them explicitly. Unassigning floating IPs is even impossible from
nova, so maybe we should not be concerned about this issue. It just
seemed weird that I can only delete a VM through OCCI once I've failed
to delete it's floating IP. If you agree we can close this issue, as I
am not particularly fond of auto-assigned floating IPs anyhow, and
because of the above.

Cheers,
Björn
