Hi,

I think this has been covered on other lists - and is apparently "normal" 
(i.e. cosmetic).

I've installed a number of FBSD10 boxes recently, and they all seem to idle 
at around that (even when doing absolutely nothing) - I did post about it 
and was told it was just cosmetic... It certainly seems to be cosmetic.

If it's the same issue - I'd guess it's not bhyve related...

"
last pid:  1294;  load averages:  0.42,  0.32,  0.27 
up 1+20:44:55  11:47:16
18 processes:  1 running, 17 sleeping
CPU:  0.0% user,  0.0% nice,  0.0% system,  0.1% interrupt, 99.9% idle
"

That's from a bare metal amd64 10.0-RELEASE-p9 box with no services / users 
on it.

Thinking about it - we had the same 'symptom' on a Xen based FBSD 10 box as 
well...
