What happens is that it gets preempted a few times while running a
particular function, say do_softirqd(), or kvm_arch_vcpu_ioctl_run().
Now, when this function ends, it prints the wall-time delay between
start and end of that function, instead of the task-time delay.
So by having been preempted several times, that gets inflated.
That said, the output is slightly 'buggy' in that is seems to miss
context switches at times:

There's 2 preemptions in there, accounting for perhaps 15ms
Then there's about 20 __wake_up()s in there (wth do those come from?)
accounting for 5ms each, totaling 100ms.
There's a scheduler_tick() in there but no IRQ entry ?!
All in all its very hard to get to the total of 250ms.
I suspect __vcpu_run() and vcpu_enter_guest() get inlined, and we might
just be looking at time spend in the guest... bit hard to tell for me,
as this is the first time ever I looked at all this kvm code.
Is there a way to add a wall-time column to this output so that we can
see where the time goes?
Another something nice would be to have ctx switches like:
foo-1 => bar-2 ran: ${time foo spend on the cpu} since: ${time bar spend away from the cpu}
I'll poke me a little at this function graph tracer thingy to see if I
can do that.
