There are lots of things missing: who is the owner? That IP was hardcoded, or is a lease from a vnet? To which Image belongs that disk, is it a link or a copy? Driver to copy back the disk to the datastore? I see two approaches to this: - Save all your VM templates and Image templates. Start over, and register everything, but for the Images use SOURCE instead of PATH to make use of the current files in your DS. - Upgrade to 4.6, undeploy all VMs, and delete all hosts, users, etc. you don't want to keep.
