Network delete - does it work?

asked 2012-03-08 19:47:26 -0600

When using: nova-manage --flagfile=/etc/nova/nova.conf network delete --uuid=<net_uuid>

We are seeing:

(nova): TRACE: Traceback (most recent call last): (nova): TRACE: File "/usr/local/bin/nova-manage", line 7, in <module> (nova): TRACE: execfile(__file__) (nova): TRACE: File "/opt/stack/nova/bin/nova-manage", line 2396, in <module> (nova): TRACE: main() (nova): TRACE: File "/opt/stack/nova/bin/nova-manage", line 2383, in main (nova): TRACE: fn(fn_args, *fn_kwargs) (nova): TRACE: File "/opt/stack/nova/bin/nova-manage", line 854, in delete (nova): TRACE: fixed_range, uuid) (nova): TRACE: File "/opt/stack/nova/nova/network/quantum/", line 254, in delete_network (nova): TRACE: raise exception.NetworkBusy(network=net_uuid) (nova): TRACE: NetworkBusy: Network ae1d67bf-b006-4c27-8543-04d0c408c015 has active ports, cannot delete. (nova): TRACE:

This is on account of the gateway port not getting cleaned up. I do see that the QuantumManager tries to clean up the gateway port if it's the only one remaining, but that does not seem to be happening for some reason.

I just want to check if anyone is able to delete networks successfully using the nova-manage command (specifically which have the gateway port already provisioned on them as consequence of at least one VM having attached to that network at some point).

Hi Sumit, thanks for the report. I think this is a bug. Taking a quick look, nova-manage seems to ignore the flags file and load the wrong linux_net.interface_driver. Can you try this patch?

its probably obvious, but launchpad messed up the indentation in the patch for the "+" line.

I was seeing the wrong driver being invoked as well. This patch fixes the problem, thanks Dan!
