[pve-devel] [PATCH-SERIES qemu-server v5 00/16] more robust handling of fleecing images

[Fiona Ebner <f.ebner@proxmox.com>]

Changes in v5:
* everything new in v5 except the last 3 patches
* new approach, use special config section instead of config key
* add tests and some fixes for configuration handling
* make special section handling more generic
* also check for and cancel left-over running backup job before
  detaching the fleecing images to prevent a deadlock in some
  scenarios

Record the created fleecing images in the VM configuration to be able
to remove left-overs after hard failures.

Adds a new special configuration section 'fleecing', making special
section handling more generic as preparation, as well as fixing some
corner cases in configuration parsing and adding tests.

Fiona Ebner (16):
  migration: remove unused variable
  test: avoid duplicate mock module in restore config test
  test: add parse config tests
  parse config: be precise about section type checks
  test: add test case exposing issue with unknown sections
  parse config: skip unknown sections and warn about their presence
  vzdump: anchor matches for pending and special sections
  vzdump: skip all special sections
  config: make special section handling generic
  test: parse config: test config with duplicate sections
  parse config: warn about duplicate sections
  check type: require schema as an argument
  config: add fleecing section
  fix #5440: vzdump: better cleanup fleecing images after hard errors
  migration: attempt to clean up potential left-over fleecing images
  destroy vm: clean up potential left-over fleecing images
