I see what you are conveying. So, it is possible for tboot to boot a
hypervisor (bitvisor), even though bitvisor does not support tboot.
Nevertheless, bitvisor still can not be booted by tboot. I also checked the
log that tboot produces when tboot is being loaded. The system always
reboots after the log prints out: no LCP module found, kernel is elf
format. According to the tboot spec, the log is expected to continue
printing: transfering control to ...@0x... But it does not and system
begins to reboot.
I wonder if the menuentry of tboot is configured right.
menuentry 'Tboot, with Linux 3.2.2' --class ubuntu --class gnu-linux
--class gnu --class os {
recordfail
insmod ext2
set root='(hd0,6)'
search --no-floppy --fs-uuid --set
b99ce3bb-2938-44e9-8277-cc5c8f942e81
multiboot /boot/tboot.gz tboot.gz logging=serial,vga,memory
module /boot/bitvisor.elf bitvisor.elf
module /boot/vmlinuz-3.2.2 vmlinuz-3.2.2
root=UUID=b99ce3bb-2938-44e9-8277-cc5c8f942e81 ro rootdelay=120
#multiboot /boot/bitvisor.elf bitvisor.elf
#module (hd0)+6
module /boot/initrd.img-3.2.2 initrd.img-3.2.2
module /boot/2nd_gen_i5_i7_SINIT_51.BIN 2nd_gen_i5_i7_SINIT_51.BIN
#module /boot/list.data list.data
}
Thanks!
