21.1.2
^^^^^^


Known Issues
************

* When the tempest test coverage was added for resize and cold
  migrate with neutron ports having QoS minimum bandwidth policy rules
  we discovered that the cross cell resize code path cannot handle
  such ports. See bug https://bugs.launchpad.net/nova/+bug/1907522 for
  details.


Upgrade Notes
*************

* 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.


Bug Fixes
*********

* Add support for the "hw:hide_hypervisor_id" extra spec. This is an
  alias for the "hide_hypervisor_id" extra spec, which was not
  compatible with the "AggregateInstanceExtraSpecsFilter" scheduler
  filter. See bug 1841932
  (https://bugs.launchpad.net/nova/+bug/1841932) for more details.

* Fixes bug 1892361 in which the pci stat pools are not updated when
  an existing device is enabled with SRIOV capability. Restart of
  nova-compute service updates the pci device type from type-PCI to
  type-PF but the pools still maintain the device type as type-PCI.
  And so the PF is considered for allocation to instance that requests
  vnic_type=direct. With this fix, the pci device type updates are
  detected and the pci stat pools are updated properly.
