I guess you are using UEFI system.  Booting from GNU GRUB2 like
following is for legacy BIOS system:

------------------------------------------------------------
menuentry 'BitVisor' {
    # For BIOS system ONLY
    set root=(hd0,gpt2)
    multiboot bitvisor.elf
    module module1.bin
    module module2.bin
}
------------------------------------------------------------

To run on UEFI system, see instructions in the
bitvisor-1.4-release-notes.txt:

------------------------------------------------------------
    To start with UEFI, build a program in the boot/uefi-loader/
    directory (a UEFI application that loads the bitvisor.elf).  Then
    put the generated binary (loadvmm.efi) and the bitvisor.elf in a
    directory that can be accessed by UEFI.  After that, make the
    loadvmm.efi executed before an OS loader by using EFI Shell or
    UEFI firmware functions.
------------------------------------------------------------

You need mingw-w64 package in Ubuntu to build the boot/uefi-loader/.
To start from GNU GRUB2, copy the loadvmm.efi and the bitvisor.elf to
/boot/efi/ directory and use chainloader command like following:

------------------------------------------------------------
menuentry 'BitVisor' {
    # For UEFI system ONLY
    set root=(hd0,gpt1)
    chainloader /loadvmm.efi
}
------------------------------------------------------------
