Reference documentation and code samples for the Compute V1 Client class AdvancedMachineFeatures.
Specifies options for controlling advanced machine features. Options that would traditionally be configured in a BIOS belong here. Features that require operating system support may have corresponding entries in the GuestOsFeatures of an Image (e.g., whether or not the OS in the Image supports nested virtualization being enabled or disabled).

Methods
__construct
Constructor.
Parameters
Name
Description
data
array
Optional. Data for populating the Message object.
↳ enable_nested_virtualization
bool
Whether to enable nested virtualization or not (default is false).
↳ enable_uefi_networking
bool
Whether to enable UEFI networking for instance creation.
↳ performance_monitoring_unit
string
Type of Performance Monitoring Unit requested on instance. Check the PerformanceMonitoringUnit enum for the list of possible values.
↳ threads_per_core
int
The number of threads per physical core. To disable simultaneous multithreading (SMT) set this to 1. If unset, the maximum number of threads supported per core by the underlying processor is assumed.
↳ turbo_mode
string
Turbo frequency mode to use for the instance. Supported modes include: * ALL_CORE_MAX Using empty string or not setting this field will use the platform-specific default turbo mode.
↳ visible_core_count
int
The number of physical cores to expose to an instance. Multiply by the number of threads per core to compute the total number of virtual CPUs to expose to the instance. If unset, the number of cores is inferred from the instance's nominal CPU count and the underlying platform's SMT width.
getEnableNestedVirtualization
Whether to enable nested virtualization or not (default is false).
