Title:
Some Neutron plugins might miss network-vif-* events
Status in OpenStack Neutron (virtual network service):
Expired
Status in OpenStack Compute (Nova):
Invalid
Bug description:
This has been observed with the VMware NSX plugin, but in theory this
issue might occur with every Neutron plugin when the notifications to
nova are enabled.
In a nutshell the issue is that nova needs to receive a network-vif-
plugged even from neutron in order to be able to boot an instance. On
the other hand in some cases VIF unplug/plug events might be fairly
quick, and thus the neutron side might not be aware at all of the
status change and not send any event.
As a consequence, the instance will not boot even if its VIF are
correctly plugged.
This bug is currently being assigned both neutron and nova because:
- it might deemed a plugin problem. If the plugin is not smart enough to
handle VIF plug/unplug notifications than it's not worth using the notification
mechanism exposed by nova
- the nova side might add an optional poll mechanism which could run
alongside the mechanism waiting for an event and periodically poll neutron to
get the VIF status.
