Expand description

Struct used in PATCH /machine-config API call. Used to update MachineConfig in VmResources. This struct mirrors all the fields in MachineConfig. All fields are optional, but at least one needs to be specified. If a field is Some(value) then we assume an update is requested for that field.

Fields§

§vcpu_count: Option<u8>

Number of vcpu to start.

§mem_size_mib: Option<usize>

The memory size in MiB.

§smt: Option<bool>

Enables or disabled SMT.

§cpu_template: Option<StaticCpuTemplate>

A CPU template that it is used to filter the CPU features exposed to the guest.

§track_dirty_pages: Option<bool>

Enables or disables dirty page tracking. Enabling allows incremental snapshots.

§huge_pages: Option<HugePageConfig>

Configures what page size Firecracker should use to back guest memory.

§enable_nested_virt: Option<bool>

Enables nested virtualization features when supported by the host.

Implementations§

Source§

impl MachineConfigUpdate

Source

pub fn is_empty(&self) -> bool

Checks if the update request contains any data. Returns true if all fields are set to None which means that there is nothing to be updated.
