Verify number of cores used by a zone

Question

Hi there,
I have a need to limit the number of cores allocated to a zone due to licensing model of a third-party software.
I used 'zone.cpu-cap' to limit the number of CPUs to 1. See below.
add rctl
set name=zone.cpu-cap
add value (priv=privileged,limit=100,action=deny)
endWhat does above configuration mean on a multi-core server such as a T5240 that has 2 x 4-core processors, with 48 virtual processors per physical processor?
Is the zone limited to 1 core or to 1 virtual processor?
How does one verify the number of cores allocated to a zone?
For reference, the processor configuration of the server is shown below:
$ uname -i
SUNW,T5240
shen@b1osdtsun02:/export/home/shen$ psrinfo -pv
The physical processor has 48 virtual processors (0-7 16-31 40-63)
  UltraSPARC-T2+ (chipid 0, clock 1165 MHz)
The physical processor has 48 virtual processors (64-71 80-119)
  UltraSPARC-T2+ (chipid 1, clock 1165 MHz)
$

Answer 1

We did that.
We capped the number of cpu to 1, but, psrinfo is still showing hundreds of on-line processors.
A sample is shown below
$ psrinfo -v | more
