The HV_VTL data type represents a Virtual Trust Level (VTL) identifier used in the hypervisor's security model. VTLs provide different levels of trust and isolation within a partition, enabling secure execution environments.
Syntax
typedef UINT8 HV_VTL;
The HV_VTL is an 8-bit unsigned integer that identifies a Virtual Trust Level. Valid VTL values range from 0 to 15.
Higher numbered VTLs have greater privilege and can access resources from lower numbered VTLs, but not vice versa.
