Spirit, I like this idea.
One additional suggestion:
NBD should be over SSH unless "migration_unsecure: 1" is set in datacenter.cfg
Yes,sure, no problem.
I think I'll try to work on it this month, as it seem that proxmox users need it
I think it's not a too big task, we have already almost all we need it to implemented this.
(I just need to push some other patches before that, so I think for the end of octobre it should be ready)
