Title:
changes-since timestamp is not updated after making network changes
Status in OpenStack Compute (Nova):
New
Bug description:
When dynamically adding and removing ports from a VM, the changes do
not cause the server timestamp to be updated. This causes the
v2/{tenant_id}/servers?changes-since={timestamp} REST API call to
return an unchanged timestamp. Thus, it appears that nothing has
changed for VM, despite the fact that the network configuration has
changed.
When using nova-network changes to the networking configuration using
that approach did cause the timestamp to be updated.
As users are being encouraged to move from nova-network to quantum
(BluePrint https://blueprints.launchpad.net/quantum/+spec/nova-to-
quantum-upgrade) this change in functionality could be seen as a
regression and could break any utilities that are expecting to see a
change in the server time stamp when changes are made to the network.
A similar bug to this one was addressed:

The issue is easy to recreate:
