pretty much anything which may wake up the guest. The nics for example
for wake-on-lan. I'm not sure whenever they care about the runstate at
Mouse and keyboard ignore events when the guest is stopped so if you
type into a vnc client for a stopped guest the events wouldn't get
queued up and cause unwanted effects when unpausing the guest. When
suspended we want forward the events though so wakeup-by-keyboard works.
Not sure whenever we have simliar logic elsewhere (like stop queuing
network packets when the guest doesn't run).
