Line Policy - Underhill command line policy.
- Imported
Region Descriptor - Describes a region of guest memory that has been imported into VTL2.
- Imported
Regions Page Header - The header field of the imported pages region page.
- Linux
Info - Measured config about linux loaded into VTL0.
- Page
Region Descriptor - Describes a region of guest memory.
- Paravisor
Command Line - Command line information. This structure is an exclusive measured page.
- Paravisor
Measured Vtl0 Config - Paravisor measured config information for vtl 0. Unlike the previous loader block which contains dynamic parameter info written by the host, this config information is known at file build time, measured, and deposited as part of the initial launch data.
- Paravisor
Measured Vtl2 Config - Paravisor measured config for vtl2.
- Supported
Vtl0 Load Info - Measured config about what this image can support loading in VTL0.
- Uefi
Info - Measured config about UEFI loaded into VTL0.

- PARAVISOR_
MEASURED_ VTL2_ CONFIG_ REGION_ PAGE_ COUNT - Count for vtl 2 measured config region size.
- PARAVISOR_
MEASURED_ VTL2_ CONFIG_ SIZE_ PAGES - Size in pages of VTL2 specific measured config
- PARAVISOR_
RESERVED_ VTL2_ PAGE_ COUNT_ MAX - Total size of the reserved vtl2 range.
- PARAVISOR_
RESERVED_ VTL2_ SNP_ CPUID_ PAGE_ INDEX - The page index to the first SNP CPUID page.
- PARAVISOR_
RESERVED_ VTL2_ SNP_ CPUID_ SIZE_ PAGES - Size in pages for the SNP CPUID pages.
- PARAVISOR_
RESERVED_ VTL2_ SNP_ SECRETS_ PAGE_ INDEX - The page index to the first SNP secrets page.
- PARAVISOR_

UNMEASURED_ VTL2_ CONFIG_ REGION_ BASE_ INDEX - Base index for the unmeasured vtl 2 config region
- PARAVISOR_
UNMEASURED_ VTL2_ CONFIG_ REGION_ PAGE_ COUNT_ MAX - The maximum size in pages of the unmeasured vtl 2 config region.
- PARAVISOR_
VTL0_ MEASURED_ CONFIG_ BASE_ PAGE_ AARC H64 - The physical page number for where the vtl 0 measured config is stored, aarch64. Not obvious about guaranteed existence. 16MiB might be a reasonable assumption as:
- PARAVISOR_
VTL0_ MEASURED_ CONFIG_ BASE_ PAGE_ X64 - The physical page number for where the vtl 0 measured config is stored, x86_64. This address is guaranteed to exist in the guest address space as it is where the ISR table is located at reset.
- PARAVISOR_
VTL2_ CONFIG_ REGION_ PAGE_ COUNT_ MAX - The maximum size in pages out of all isolation architectures.
