It is not surprising that the dnsmasq and the bridges aren't brought down when you delete the network with nova-manage (database manip. tool, and all that). This should be resolved when network-delete for the nova python client is implemented (see https://bugzilla.redhat.com/show_bug.cgi?id=957495). Until then, the admin will need to manually tear down the bridge and dnsmasq instance. |
