Comment 5 for bug 1827746

it depnes on how the comptue node is down and if the queue still exists wheater it would get cleand up eventualy. until https://bugs.launchpad.net/oslo.messaging/+bug/1661510 is fix i dont think we can assume that it will definetly get recived and acted on when the compute node comes back up.

on master at least if we detach the port on master the network info cache should get updated with the correct value due to the recent force heal change and that should mean if the vm was stoop and then started it would be started without the port.

to add support for local delete we would need a perodic or a starup task that force referesh the info cache form neutron and checks every vm and determing if the xml should be modified to match the info cache interface built form neutorn. it can be dont but i dont think we can rely on the rpc to do it.
