Public bug reported:
The proc(5) man page only documents nine fields for the "cpu" line in
/proc/stat:
...
Since Linux 2.6.24, there is a ninth column, guest, which
is the time spent running a virtual CPU for guest operat‐
ing systems under the control of the Linux kernel.
...
On my Ubuntu 12.04 system with Linux 3.2.0-24-generic-pae there are ten fields:
cpu 70741124 519708 27538725 1384358154 33244926 9450 248630 0 0 0
According to show_stat() function in fs/proc/stat.c in linux-3.2.0
source package, the tenth field is the "guest_nice" tick value. It would
be nice if this would be documented in the man page. I'm not quite sure
what the guest_nice value actually means, though.
