upgrade:

|
The default for ``[glance] num_retries`` has changed from ``0`` to ``3``.
|
|
The option controls how many times to retry a Glance API call in response
|
|
to a HTTP connection failure. When deploying Glance behind HAproxy it is
|
|
possible for a response to arrive just after the HAproxy idle time. As a
|
|
result, an exception will be raised when the connection is closed resulting
|
|
in a failed request. By increasing the default value, Nova can be more
|
|
resilient to this scenario were HAproxy is misconfigured by retrying the
|
|
request.
