No, I did not test suspend/resume.

I really don't see why it should get into Closed on suspend, but anyway, is 
this really hapenning? I could not find any switch to Closed into suspend's 
code, neither on resume.

How to test suspend/resume on a domU? It does not have /sys/power/state 
neither /proc/sleep.
