Struct Vtl2LunBuilder

Source 
pub struct Vtl2LunBuilder { /* private fields */ }
Expand description

A builder for a VTL2 LUN, which is a storage device presented from VTL2 to the guest.

A LUN can be one of two flavors: a disk or a DVD (really a virtual optical device, since it’s a CD-ROM when presented over IDE). A DVD can be empty (backed by no physical devices) or it can be backed by one or more physical devices. A disk must be backed by one or more physical devices. (This is not checked, since there may be interesting test cases that need to violate these requirements.)

Implementations§

Source§

impl Vtl2LunBuilder

Source

pub fn disk() -> Self

Creates a new disk LUN builder with default values. Here “disk” is as opposed to NOT a DVD.

Source

pub fn dvd() -> Self

Creates a new dvd LUN builder with default values. Here “dvd” is as opposed to NOT a disk.

Source

pub fn with_location(self, location: u32) -> Self

Guest visible location of the device (aka a guest “LUN”)

Source

pub fn with_physical_devices( self, physical_devices: Vec<Vtl2StorageBackingDeviceBuilder>, ) -> Self

The physical devices backing the LUN.

Overwrites any current physical backing device configuration (one or many).

Source

pub fn with_physical_device( self, physical_device: Vtl2StorageBackingDeviceBuilder, ) -> Self

The single physical device backing the LUN.

Overwrites any current physical backing device configuration (one or many).

Source

pub fn with_chunk_size_in_kb(self, chunk_size_in_kb: u32) -> Self

For striped devices, the size of the stripe chunk in KB.

Source

pub fn build(self) -> Lun

Builds the LUN into the protobuf type used by VTL2 settings.
