Struct MicrovmConfig 

pub struct MicrovmConfig {
    pub vcpu_count: u8,
    pub memory_mb: u32,
    pub cpu_quota_us: Option<u64>,
    pub kernel_path: PathBuf,
    pub rootfs_path: PathBuf,
}

Configuration for a single microVM instance.

The configuration describes the guest CPU and memory shape plus the host-side assets required to boot the guest kernel and root filesystem. It is validated before any backend is created.

Fields

vcpu_count: u8

Number of virtual CPUs exposed to the guest.

memory_mb: u32

Guest memory size in mebibytes.

cpu_quota_us: Option<u64>

Optional CPU time quota in microseconds for backends that support CPU throttling.

kernel_path: PathBuf

Path to the guest kernel image on the host.

rootfs_path: PathBuf

Path to the gzip-compressed guest rootfs image on the host.

Implementations

impl MicrovmConfig

pub fn memory_bytes(&self) -> Result<usize, MicrovmError>

Returns the configured guest memory size in bytes.

The conversion checks for arithmetic overflow and for platforms where the requested memory size cannot fit into usize.

pub fn validate(&self) -> Result<(), MicrovmError>

Validates the base microVM configuration before backend creation.

Validation rejects zero vCPU count, memory below the minimum supported guest size, empty asset paths, and missing kernel or rootfs files.

Trait Implementations

impl Clone for MicrovmConfig

fn clone(&self) -> MicrovmConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MicrovmConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MicrovmConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MicrovmConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MicrovmConfig

fn eq(&self, other: &MicrovmConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for MicrovmConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
