Hello,
Thank you for posting in Q&A forum.
Failure to start the virtual machine after a successful restore may be caused by the following failures:
- The network adapter name is inconsistent with the new host
- The saved state data of the original host and the new host conflict in computer configuration.
It is recommended to refer to the following links: Restored Hyper-V virtual machines won't start - Windows Server | Microsoft Learn
I hope the information above is helpful.
Best Regards,
Yanhong Liu
