Struct VmCapabilities 

pub struct VmCapabilities {
    pub pause_resume: bool,
    pub snapshots: bool,
    pub vsock: bool,
    pub tap_networking: bool,
}

Capabilities that a backend may or may not support.

Used by consumers to check what operations are available before attempting them. For example, WASM backends won’t support snapshots.

Fields

pause_resume: bool

Can pause/resume vCPUs (Firecracker: yes, WASM: no).

snapshots: bool

Can create/restore memory snapshots (Firecracker: yes, Docker: checkpoints, WASM: no).

vsock: bool

Supports vsock guest communication (Firecracker: yes, others: typically no).

tap_networking: bool

Supports TAP-based networking (Firecracker/Docker: yes, WASM: no).
