Struct VirtioDeviceConfig 

pub struct VirtioDeviceConfig {
    pub device_type: VirtioDeviceType,
    pub config: Vec<u8>,
    pub path: Option<String>,
    pub read_only: bool,
    pub tag: Option<String>,
    pub net_fd: Option<i32>,
    pub mac_address: Option<String>,
}

VirtIO device configuration for attaching to a VM.

Fields

device_type: VirtioDeviceType

Device type.

config: Vec<u8>

Device-specific configuration.

path: Option<String>

Path to device (for block/fs devices).

read_only: bool

Whether the device is read-only.

tag: Option<String>

Tag for filesystem devices.

net_fd: Option<i32>

File descriptor for file-handle-based network attachment.

mac_address: Option<String>

Optional MAC address for network devices.

Implementations

impl VirtioDeviceConfig

pub fn block(path: impl Into<String>, read_only: bool) -> Self

Creates a new block device configuration.

pub const fn network() -> Self

Creates a new network device configuration with NAT attachment.

pub fn network_with_mac(mac_address: impl Into<String>) -> Self

Creates a new network device configuration with NAT attachment and an explicit MAC address.

pub const fn network_file_handle(fd: i32) -> Self

Creates a network device configuration with file-handle attachment.

The VZ framework side uses one connected datagram socket file descriptor for bidirectional frame I/O.

pub fn network_file_handle_with_mac( fd: i32, mac_address: impl Into<String>, ) -> Self

Creates a network device configuration with file-handle attachment and an explicit MAC address.

Use this when the MAC must match an external interface (e.g. vmnet) so that bridge FDB lookups resolve correctly.

pub const fn console() -> Self

Creates a new console device configuration.

pub fn filesystem( path: impl Into<String>, tag: impl Into<String>, read_only: bool, ) -> Self

Creates a new filesystem device configuration.

pub const fn vsock() -> Self

Creates a new vsock device configuration.

pub const fn entropy() -> Self

Creates a new entropy device configuration.

impl VirtioDeviceConfig

pub const fn balloon() -> Self

Creates a new balloon device configuration.

The balloon device allows dynamic memory management by inflating (reclaiming memory from guest) or deflating (returning memory to guest).

Trait Implementations

impl Clone for VirtioDeviceConfig

fn clone(&self) -> VirtioDeviceConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VirtioDeviceConfig

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VirtioDeviceConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for VirtioDeviceConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
