I clearly missed the discussion.  Is this actually useful?  In practice,
won't you want the log from the guest?  What makes a virtual guest
different from a physical guest?

Guest watchdog functionality might be useful, but that's simpler to
implement via a virtio watchdog device, and more effective to implement
via a host facility that actually pings guest functionality (rather than
the kernel).

Cheers,
Rusty.
