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 x86 platform for 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.
