I have hit the bug, with migrating 10vm at the same time, and something bad happen, all target process stopped

another way,
you have 40running vm, do a killall -9 kvm , I have 100% scope running. (can reproduce always)


Sound like a race when systemd need to cleanup an amount of process at the same time.

It would be nice if we find a way to reproduce the problem. I already tried, but 
I 
cannot reproduce. 

But yes, we can add such workaround.
