Struct VhostUserFsHandle 

pub struct VhostUserFsHandle {
    pub socket: OwnedFd,
    pub tag: String,
    pub num_queues: Option<u16>,
    pub queue_size: Option<u16>,
}

Handle for a vhost-user virtio-fs device.

The frontend owns the config space (tag + num_request_queues) and does not negotiate VHOST_USER_PROTOCOL_F_CONFIG with the backend. The tag is specified by the host, matching the behavior of cloud-hypervisor.

Fields

socket: OwnedFd

Connected Unix socket fd to the vhost-user backend.

tag: String

The mount tag exposed to the guest (max 36 bytes).

num_queues: Option<u16>

Number of request queues (default 1 in resolver).

queue_size: Option<u16>

Queue size for all queues (default 1024 in resolver).
