[pve-devel] vm migration + storage migration with ndb workflow notes

I think the main feature is indeed live migrate from a local non shared storage to a another remote local non shared storage.

I see another usage (for my own need), migrate between 2 remote datacenters (1proxmox cluster across both), with a local san on each datacenter.
Each datacenter can use differents storage, with differents protocol (nfs -> iscsi for exemple).


What do you mean by ("changing storage is not really needed?"). Do you mean changing storage format ? (local raw -> remote local lvm by example)
Because,For online remote storage migration, with ndb, it's easy to mirror from any source storage to any remote storage.

Yes, I would also like to do that after copy/clone. 

Besides, I think the whole thing gets to complex. 

We only want to be able to migrate local disks (changing storage is not really needed?). 
I guess that would make 'remote' migrate much easier?
