This series aims to allow offline migration with '--targetstorage'
and improve handling unsued/orphaned disks when migrating.
It also makes it possible to migrate volumes between storages
with different naming schemes if the same format is supported
by both storages (e.g. migrating raw volumes between storages with
a path and lvm storages).
The series is split up as follows:
#1 to #4: move drive-related code into its own module
#5 to #14: generalize snapshot_foreach_volume and add abstract volume helpers
#15 to #21: introduce allow-rename parameter for import and change
storage_migrate
interface to use options
#22 to #26: allow offline migration and use allow-rename parameter
#27 to #28: translate volume name for migration to a different storage type
See [0] for the previous version/RFC.
Changes to v1:
* Split off drive-related code into its own module
* Make snapshot_foreach_volume more flexible
* update_volume_ids: update the config in place
* Introduce allow-rename option to 'pvesm import' and
only rename when explicitly requested
* Bump APIVER and APIAGE for the storage interface changes
* Create simple helpers to translate a volume name between
different storage types

qemu-server:
Fabian Ebner (13):
Replace drivename_hash with drivedesc_hash
Use parse_drive for EFI disk
print_drive: Use $skip to avoid the need to copy the hash
Create Drive.pm and move some drive-related code there
parse_drive: Allow parsing vmstate volumes
Implement volume-related helpers
Extend snapshot_foreach_volume to allow different selections of
volumes
Use new storage_migrate interface
Take note of changes to the volume IDs when migrating and update the
config
Allow specifying targetstorage for offline migration
Update volume IDs in one go
sync_disks: use allow_rename to avoid collisions on the target storage
sync_disks: be more verbose if storage_migrate fails
