Well I don't get this of course yet. I guess it's useful for some
workloads, but VM being blocked for 2 minutes breaks lots of workloads.
Guests with 30 devices do exist, we are talking about an hour to start
these guest.
I wonder whether we should instead just provide some guidance on how long
is it ok for reset to take? Say if we want to address kata, <100ms boot
time, I guess we can recomment not more than 10ms? Anything
more would trigger at least a warning.
