What you have done has been successful.The good news is the conversion has succeeded. the bad news is that you have hit a different issue. Unfortunately I don't know what is wring this time.
The loading messages mention kvm, but you said it is a physical machine (btw converter doesn't convert KVM machines). Is it a KVM server by chance? Can you pls give more info on peculiarities of the source machine. Also upload the log bundle, it might be useful.
