[libvirt] [PATCH 0/5] Fix starting of VMs with backing chains containing unknown backing file specification



When a backing chain element specifies a parent in a format not known to libvirt
we'd fail to start the VM as the chain would appear broken.

To prevent this happening introduce a new disk type to collect
unknow format specs and avoid startup failures with such disk type.

Peter Krempa (5):
  util: storage: Convert disk locality check to switch statement
  conf: Introduce raw disk string passthrough
  conf: Mark backing chain ending with "raw" volume as broken
  tests: Add tests for disk type 'raw'
  utils: storage: Fall back to "raw" disk  on backing store parse
    failure
