Expand description

Configuration parameters supplied to UhProtoPartition::new.

These do not include runtime resources.

Fields§

§isolation: IsolationType

The isolation type for the partition.

§hide_isolation: bool

Hide isolation from the guest. The guest will run as if it is not isolated.

§lower_vtl_memory_layout: &'a MemoryLayout

The memory layout for lower VTLs.

§topology: &'a ProcessorTopology

The guest processor topology.

§cvm_cpuid_info: Option<&'a [u8]>

The unparsed CVM cpuid info.

§snp_secrets: Option<&'a [u8]>

The unparsed CVM secrets page.

§env_cvm_guest_vsm: bool

Whether underhill was configured to support guest vsm for CVMs

§vtom: Option<u64>

The virtual top of memory for hardware-isolated VMs.

Must be a power of two.

§handle_synic: bool

Handle synic messages and events.

On TDX, this prevents the hypervisor from getting vmtdcall exits.

§no_sidecar_hotplug: bool

Do not hotplug sidecar VPs on their first exit. Just continue running the VP remotely.

§use_mmio_hypercalls: bool

Use MMIO access hypercalls.

§intercept_debug_exceptions: bool

Intercept guest debug exceptions to support gdbstub.
