Virtual Secure Mode (VSM) is a set of hypervisor capabilities and
enlightenments offered to host and guest partitions which enables
the creation and management of new security boundaries within
operating system software.
VSM achieves and maintains isolation through Virtual Trust Levels
(VTLs). Virtual Trust Levels are hierarchical, with higher levels
being more privileged than lower levels. VTL0 is the least privileged
level, and currently only other level supported is VTL2.
Select this option to build a Linux kernel to run at a VTL other than
the normal VTL0, which currently is only VTL2. This option
initializes the kernel to run in VTL2, and adds the ability to boot
secondary CPUs directly into 64-bit context as required for VTLs other
than 0. A kernel built with this option must run at VTL2, and will
not run as a normal guest.
If unsure, say N
