Hello

I have a few bhyve instances running that all seem to have a higher load average than what would seem normal for a system that is idle.


The host is running FreeBSD 10.1-BETA3 #2 r272300.

The guests are all running FreeBSD 10.0-RELEASE-p9 updated via freebsd-update.

The head of the top output inside a guest:

last pid: 6109; load averages: 0.41, 0.38, 0.39 up 1+14:27:48 09:56:25
24 processes:  1 running, 23 sleeping
CPU:  0.0% user,  0.0% nice,  0.0% system,  0.0% interrupt,  100% idle
Mem: 6392K Active, 437M Inact, 379M Wired, 420M Buf, 3120M Free
Swap: 4096M Total, 4096M Free

I would have expected a load average around 0.00. Am I doing something wrong or is there something else that could be causing this?

The guests all seem responsive and otherwise work fine.

Apart from this I haven't encountered any problems when working with bhyve. It's nice and easy to work with. Thanks a lot for bringing this to FreeBSD.
