upgrade:

The default value for the ``metadata_workers`` configuration option
|
|
has changed to 2 for the ML2/OVN driver. For ML2/OVS the default
|
|
value remains the same. Each driver has different approaches when
|
|
serving metadata to the instances and the previous default value of
|
|
"<number of CPUs> / 2" did not make sense for ML2/OVN as the OVN
|
|
metadata agents are distributed running on Compute nodes instead of
|
|
Controller nodes. In fact, the previous default value could cause
|
|
scalability issues with ML2/OVN and was overwritten by the deployment
|
|
tools to avoid problems.
