Failed to start Hyper-V VM on windows 11

Question

Hi, I have migrated from Windows 10 to 11. I also upgraded VM config version to 11. But one of my VM fails to start with error message : Failed to start worker process: Cannot create a file when that file already exists. (0x800700B7) What should I do to make my VM up again? Thank you

Answer 1

Hi, Please delete the saved state for this virtual machine by right-clicking on the virtual machine and selecting the Delete Saved State menu item. If this does not work, you can remove the virtual machine and create a new VM with the existing virtual VHD/VHDX file.
