Virtual Slim bootloader (vSBL) is the virtual bootloader supporting booting
Virtual Slim Bootloader (vSBL) is the virtual bootloader supporting booting
of the User VM on the ACRN hypervisor platform. The vSBL design is derived
from Slim Bootloader, which follows a staged design approach that provides
hardware initialization and launching a payload that provides the boot
logic.
The vSBL image is installed on the Service OS root filesystem by the
service-os bundle, in ``/usr/share/acrn/bios/``. In the current design,
the vSBL supports booting Android guest OS or Linux guest OS using the same
vSBL image. For Android VM, the vSBL will load and verify trusty OS first,
and trusty OS will then load and verify Android OS according to Android OS
verification mechanism.
