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

[Alexandre DERUMIER]

>>OK, I see. But then template copy/clone only works if the template if offline?

I have also add online vm cloning feature, without template.

But yes, with template flag on current, vm is offline.

My disk copy code, just use qemu-img if offline or drive-mirror if online.


I reuse same copy code for "qm move", 
that's why I think we can keep qemu-img for offline as implementation is already done.

OK, I see. But then template copy/clone only works if the template if offline? 

(yes, I know - I should read your code instead)
