In general, the files must be in an EFI system partition that is
usually the first partition (hd0,gpt1) and mounted at /boot/efi in
Linux.  Only FAT partitions are accessible by loadvmm.efi unless
additional file system drivers for UEFI is installed.  The --force
option for chainloader command is not needed.

The 8000000000000003 is an error code of UEFI.  According to
edk/Foundation/Efi/Include/EfiError.h the error is EFI_UNSUPPORTED.
The loadvmm.efi could not get a handle of the Simple File System
Protocol because the GNU GRUB loads the loadvmm.efi from a raw
partition using its own file system implementation instead of using
the Simple File System Protocol of UEFI.
