You're basically saying that if something isn't connected, drop them. If it is connected, do a monitor_printf() such that you're never queuing events. Entirely reasonable and I've considered it.
However, I do like the idea though of QEMU queuing events for a certain period of time. Not everyone always has something connected to a monitor. I may notice that my NFS server (which runs in a VM) is not responding, VNC to the system, switch to the monitor, and take a look at the event log. If I can get the past 10 minutes of events, I may see something useful like a host IO failure.
"10 minutes" is the red flag for me. Why not 5 minutes? 60 minutes? 24 hours? The fact that it's so arbitrary suggests it doesn't really belong. If you care, you can attach a logging daemon that keeps the last 10 minutes worth of data... -- Hollis Blanchard IBM Linux Technology Center
