Struct VmClock 

pub struct VmClock {
    pub guest_address: GuestAddress,
    /* private fields */
}

VMclock device

This device emulates the VMclock device which allows passing information to the guest related to the relation of the host CPU to real-time clock as well as information about disruptive events, such as live-migration.

Fields

guest_address: GuestAddress

Guest address in which we will write the VMclock struct
