Yes, I known. 
But It's not too much different, we can reuse code, just using nbd as target instead a volume file/device.

My proposal was to reuse "qm migrate",to avoid having 2 apis for migrate storage(1 for target storage on localhost, 1 for target storage on remote host)

if hosttarget = sourcetarget, then we simply migrate the disks
if hosttarget != sourcetarget, we mirror the disks with nbd (only if the storage is non-shared on both hosts), then we migrate the vm.

Maybe Dietmar have you an opinion about this ?

I see your point. This particular situation is not handle in my code 
since it will only migrate between common attached storage backends. The 
case of migrating to an unattached storage is in my opinion a completely 
different usecase.
