blockDeviceIdentifier

Declaration

var blockDeviceIdentifier: String { get set }

Discussion

Use blockDeviceIdentifier to name devices so they’re more discoverable in the Linux guest. The identifier must be an ASCII encodable string of 20 bytes or less.

Validate the identifier string using validateBlockDeviceIdentifier(_:) before attempting to set this property, for example:

let idString = "ProjectData"
do {
    try VZVirtioBlockDeviceConfiguration.validateBlockDeviceIdentifier(idString)
    blockDeviceIdentifier = idString
} catch {
    // Handle error as appropriate.
    throw error
}

In a Linux guest, device identifiers are visible in the /dev/disk/by-id/ directory.
