Event-driven would be more efficient and more responsive than periodic

That assumes that an event can be generated, which may not be possible
with a guest os crash (if, for example, it was in an infinite loop with
interrupts disabled).

It wouldn’t be a “guest OS”, it would be a “guest container”. Remember,
the processes in the container are isolated from the host, but the host
continues to have full visibility into the guest.

For a container, guest termination is synonymous with termination of its
guest-specific “init” (container-internal PID 1) process. A host watcher
process can monitor several of these at once via the Linux pidfd mechanism
