[pve-devel] [RFC v2 storage 0/6] import/export api

[Wolfgang Bumiller]

Changes to v1:
  rebased onto current master
  export: don't unlink on success...

- Original cover letter:

This is a first (working) draft of an import/export interface.

The idea is to provide the storage-side functionality required and
implemented twice - both by storage_migrate() and the replication patch
set's volume_send() plugin call.

The third patch replaces storage_migrate()'s ZFS case with an almost
storage agnostic implementation. The patches following it add transfer
format queries and the 6th patch then turns this into a storage type
independent implementation.

Thoughts?

Wolfgang Bumiller (6):
  pvesm: import/export commands
  pvesm: add delsnapshot command
  migrate: use pvesm import/export for zfs
  migrate: snapshot parameter for incremental transfer
  api: add import/export format querying
  migrate: query transfer stream formats
