I haven't seen it that I recall, but a Google search suggests that it
comes from load balancing when you're "running tickless".

The scheduler is trying to tell you something (because the
scale_rt_power() function is in the scheduler), but the context is
lost.
Does this guest have multiple CPUs?
Also, have you made any tuning changes over its life? (Things handled
by 'sysctl' or /etc/sysctl.conf.)
What is the output of ...
sysctl -a | grep sched
Also, what do your boot parms look like? (Look for HZ timer and other
scheduler tweaks.)
