The behavior for retention of VIF interface attachments has changed.
If your use of the BareMetal service is reliant upon the behavior of
the VIFs being retained, which was introduced as a behavior change
during the Ocata cycle, then you must update your tooling to explicitly
re-add the VIF attachments prior to deployment.
fixes:
- |
Removes all records of VIF attachments upon the teardown of a deployed
node. This is in order to resolve issues related to where it is
operationally impossible in some circumstances to remove a VIF
attachment while a node is being undeployed as the Compute service
will only attempt to remove the VIF for five minutes.
