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
a 'path' and storages without if the target storage uses the standard
naming scheme and the source format is supported (e.g. migrating raw
volumes between storages with a path and lvm storages).
It also adds an apiinfo call to pvesm that can be used to determine
APIVER and APIAGE of the remote node and does some general refactoring
regarding volume iterators.
The series is organised as follows:
#1-#3 make use of volume-related helpers
These are not needed for the rest of the series.
#4-#7 storage_migrate interface change
Dependencies: qemu-server,guest-common,container -> storage
#8-#15 do the work to allow offline --targetstorage and to avoid collisions
#14 is optional, but consolidates updating the volume IDs in the config
Dependencies: qemu-server -> guest-common,storage
#16-#19 further improvements
#19 makes migrating raw between dir and lvm possible
Changes from v4:
* rebased remaining patches on current master
which made three non-trivial changes necessary:
* replaced a newly introduced foreach_drive
* increased storage API bump
* adapted check in cleanup_remotedisks()

qemu-server:
Fabian Ebner (10):
Switch to using foreach_volume instead of foreach_drive
Use new storage_migrate interface
Allow parsing vmstate entries
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
sync_disks: log output of storage_migrate
cleanup_remotedisks: also include those migrated with storage_migrate
