[Bug 1317695] Re: hyper-v: Unable to copy and boot Generation 2 Ubuntu 14.04 VHDs

 

There is a temporary workaround for this issue. That workaround is to:

* Rename the /boot/efi/EFI/ubuntu directory to /boot/efi/EFI/BOOT
* In the newly renamed BOOT directory, rename shimx64.efi to bootx64.efi

This should temporarily resolve the issue.

Title:
  hyper-v: Unable to copy and boot Generation 2 Ubuntu 14.04 VHDs

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  After creating a Generation 2 virtual machine, we are unable to
  shutdown the VM, copy the VHD and create a new Generation 2 virtual
  machine out of the VHD. It seems that once the copy out operation has
  occurred, the UEFI boot entry is not available on the file-system.
  This hinders scenarios where customers routinely copy VHDs to create
  new virtual machines. Root cause unknown as of now.
