Struct VirtioVsockDevice 

pub struct VirtioVsockDevice { /* private fields */ }

Virtio vsock device.

Implementations

impl VirtioVsockDevice

pub fn new( driver_source: &VmTaskDriverSource, guest_cid: u64, base_path: PathBuf, listener: UnixListener, ) -> Result<Self>

Create a new virtio-vsock device.

guest_cid is the context ID assigned to the guest.

base_path is the path prefix for Unix socket relay. For a vsock port P, the relay will attempt to connect to <base_path>_P.

listener is an pre-bound Unix listener for accepting host-initiated connections using the hybrid vsock connect protocol.
