I have no idea why it would just get stuck. 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 } ------------------------------------------------------------ </blockquote><div>Thanks for your answer, but it outputs 'FileSystemProtocol 8000000000000003' when I choose BitVisor at grub menu. This message disappers in a flash and it immediately returns back </div><div>to the grub menu. I tried to google the number 8000000000000003 but I didn't find it useful. </div><div>Here is the menu I added in /etc/grub.d/40_custom menuentry 'BitVisor' { # For UEFI system ONLY insmod chain set root=(hd0,gpt2) chainloader --force /boot/loadvmm.efi } </div><div>The bitvisor.elf file is also in /boot directory. </div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"> -- Hideki EIRAKU <<a href="mailto:hdk@igel.co.jp">hdk@igel.co.jp</a>> _______________________________________________ BitVisor-users-en mailing list <a href="mailto:BitVisor-users-en@bitvisor.org">BitVisor-users-en@bitvisor.org</a> <a href="https://www.bitvisor.org/mailman/listinfo/bitvisor-users-en" rel="noreferrer" target="_blank">https://www.bitvisor.org/mailman/listinfo/bitvisor-users-en</a> </blockquote></div> </div></div>
